Failed authorization procedure. (http-01): urn:ietf:params:acme:error:dns :: No valid IP addresses found

Having some trouble using Certbot to install an SSL certificate for your website? Getting hit with an error message that looks something like?:

Failed authorization procedure. (http-01): urn:ietf:params:acme:error:dns :: No valid IP addresses found for


The following errors were reported by the server:

Type: None
Detail: No valid IP addresses found for

Your account credentials have been saved in your Certbot
configuration directory at /etc/letsencrypt. You should make a
secure backup of this folder now. This configuration directory will
also contain certificates and private keys obtained by Certbot so
making regular backups of this folder is ideal.

Okay, so here’s what’s probably going on: You just bought your domain name, set your nameservers, uploaded a landing page to your server etc., then wham! Certbot just doesn’t want to add that little https to your URL. The issue may be that your newly registered domain name hasn’t propagated through the internet’s DNS registry yet so Certbot is having a hard time finding the corresponding IP Address for your new domain.

The solution? Just give GoDaddy or whoever else you used to register your domain a little more time update everything and try running Certbot again.

If you’d like to test this hypothesis out, try visiting your new domain through Google Chrome AND Mozilla Firefox AND/OR Apple Safari. I found that while Google Chrome could not find my new domain, Firefox found the new domain easily and displayed my placeholder landing page just fine, albeit with an “unsecure” icon indicating that the site had not yet been secured with an SSL certificate. Likewise, it appears Certbot itself can’t find the newly registered domain either, just like Google Chrome. If you happen to have multiple browsers, try visiting your domain from different browsers to see if you can duplicate what I’ve described above. If you find that your website isn’t showing up yet, give your registrar and the World Wide Web a little time to process things and try again.


The file tsc.ps1 is not digitally signed. You cannot run this script on the current system…

Run into the following bug trying to get TypeScript up and running in VSCode on your Windows machine?

The file tsc.ps1 is not digitally signed. You cannot run this script on the
current system. For more information about running scripts and setting execution policy, see
about_Execution_Policies at https:/

Okay so here’s the deal. You probably installed the TypeScript compiler using the Windows Command Prompt or possibly the built-in PowerShell terminal from within VSCode. Installing TypeScript using the Command Prompt or the built-in terminal in VSCode will both cause your system to throw the nasty error above when you actually attempt to start using the TypeScript compiler.

Okay so… then what do we need to do? Well here’s your answer:

First, uninstall TypeScript.

$ npm uninstall -g typescript

Next, open up the Windows PowerShell (not the built-in PowerShell in VSCode) making sure to run the program as an administrator. If you don’t know how to do this, search for “PowerShell” in the search bar next to the Windows Start Button in the lower left and corner of your screen. Then right-click on “Windows PowerShell” and select “Run as administrator”. From the Windows PowerShell, you can now re-install TypeScript with administrator privileges which will fix the permissions related bug mentioned above.

$ npm install -g typescript

Now go ahead and re-open your TypeScript project in VSCode and compile it like normal, and everything should work A-okay đź‘Ś.


Hello, World in Django: My Quickstart/Cheatsheet for Getting Up and Running with Django on Windows

Getting to hello, world in Django is kind of a pain. If you find yourself having some trouble getting up and running on your Windows machine and want to get to “hello, world” as quickly as possible, I hope you find my cheat sheet below helpful. This isn’t really tutorial. For that, I suggest going through the official Django Polls App Tutorial. However, if you just want a quick reference for the future, this is the guide for you!

$ cd Desktop
$ mkdir HelloDjango
$ cd HelloDjango
// Create Virtual Environment with Python's venv
$ python -m venv env
// Activate the Virtual Environment (Windows)
$ env\Scripts\activate
// Install Django
(env) $ python -m pip install Django
// Create / Update requirements.txt File
(env) $ pip freeze > requirements.txt
// Running someone else's Django App?
// See below how to install dependencies from requirements.txt file...
(env) $ pip install -r requirements.txt
// Create Django Project (Project Can Contain Many Apps)
(env) $ django-admin startproject hellodjango
// Run Django Development Server
(env) $ python runserver
// Create Django App
(env) $ cd hellodjango
(env) $ python startapp hellodjangoapp
// Connect new "App" to Project
Open the file under the hellodjango directory,
and add hellodjangoapp.apps.HellodjangoappConfig to INSTALLED_APPS
# Application definition
// Add your first view (hello, world) to hellodjangoapp/
from django.http import HttpResponse
# Create your views here.
def index(request):
return HttpResponse("hello, world")
// Create your app's file (will also need to update project after this)
from django.urls import path
from . import views
urlpatterns = [
path('', views.index, name='index'),
// Now update your project's file (notice updated import statements)
from django.contrib import admin
from django.urls import include, path
urlpatterns = [
path('', include('hellodjangoapp.urls')),
// Run development server (run from hellodjango directory)
(env) $ cd hellodjango
(env) $ python runserver
// Now visit in your web browser to see your hello, world in action
// NOTE: Apparently Django will create your requirements.txt file for you
// the first time you run the development server, so the requirements.txt
// code above is likely NOT necessary, consider removing from instructions.

How to Contribute Code to Someone Else’s GitHub Repo

Having trouble figuring out how to contribute code to someone else’s GitHub repo? Git can be quite complicated, so there’s no wonder why you might be having trouble with this. In fact, I found myself today struggling with this same issue attempting to contribute to an open source project for the first time. Thus, here I am writing this post, more or less for my own personal reference. So without further ado… How to Contribute Code to Someone Else’s GitHub Repo

First, you are going to want to fork the other user’s project. This is not intuitive at all. One would think that simply cloning the users project to your local machine and submitting changes from your local project would make the most sense, but this simply isn’t how it’s done. You are going to want to press the “fork” button on the other user’s page to get started. This is your first step.

Next, when you are ready to start working on your new feature or contribution, it’s time to create a “feature branch” which you will be using to develop your new feature or contribution. We’ll start by cloning your recently created fork to your local machine:

$ git clone

Now let’s create the new branch:

$ git checkout -b my-feature-branch

After creating your new branch, make some changes to the code on your local machine remembering to hit the “save” button in your text editor or IDE. After saving your changes, let’s stage, commit, and push your changes to your forked GitHub repository:

$ git stage .

$ git commit -m "my first open source commit"

$ git push origin my-feature-branch

Now that we’ve pushed our work to the feature branch of our forked GitHub repository, we can push the “submit pull request” button on to contribute our code to the other user’s GitHub repository. Note, we will be contributing the code from my-feature-branch on our forked repository over to the master branch of the other user’s repository. This is the default setting whenever you push the “submit pull request” button from a forked repository on GitHub assumes you are wishing to submit the pull request to the original repository which you forked.

Assuming that the other user accepts our pull request, now we will need to sync our forked repo once again with the other user’s repo. This is another one of those not-obvious quirks that I found hard to grasp at first. Once we submit a pull request from a feature branch to the other user’s master branch, our master branch on our fork will actually be out of sync with the other users master branch. So this last little gem here will let us get everything back in sync:

(Configure a remote for fork)

$ git remote add upstream

(Sync Forked Master Branch with Other User’s Master Branch)

$ git checkout master

$ git merge upstream/master

Now everything should all be in-sync. To contribute more code simply go back to step one, create a new feature branch (with a different name) and repeat the steps above.


Blocked, Banned, or Suspended by AngelList? Use Crunchbase PRO Instead

(Loose) Transcription of Episode 35 of Misadventures in Startups

[Please don’t actually read this blog post, watch the video above!]

I just included a transcription here on the blog so Google might send a little traffic my way. But if you insist…

Welcome back internet friends! Topher Pedersen here, again with more misadventures in startups. Today, I want to talk about getting blocked, banned or suspended from AngelList. AngelList— a whole lot of hype around AngelList. You’re always seeing Naval Ravikant everywhere. He was on Joe Rogan’s podcast last year. So if you’re into startups and you’re watching this video, Obviously you’re like, “Hey, how do I get into AngelList? How do I do this stuff?” And you’re on there trying to raise some money. Maybe you’ve been doing a little research and you’ve send your first messages to some angel investors and… WHAM! You get blocked, banned, suspended!

So what’s the deal with that? All right, well here’s the thing: AngelList is not for you.

AngelList, despite how they market themselves as you know, democratizing venture capital, etc. etc. is not really for you. It’s actually quite elitist.

What I mean by that is it’s not elitist in a racial or socio-economic background kind of way. But it is really is about who you know. It’s NOT about what you know. Very clichĂ© saying, but that’s honestly how AngelList operates.

So I’m assuming that if you’re reading this blog post, that this has happened to you: You signed up for AngelList, you made a profile, and then were like now what? What do I do now? It’s very much like early Facebook back in 2005 – 2006. Back then If you signed up for Facebook, you really just had a profile. There wasn’t a whole lot, other than that, and you could like send messages but that was about it. And that’s very much what AngelList is like today. You make a profile for your startup and you can message investors. But the search functionality on AngelList is not really very good. The only thing you can really do is see who your direct connections are, and maybe friends of friends (secondary connections). But if you’re like myself, and you don’t live in Silicon Valley, you don’t work for a Silicon Valley company as an engineer, you’re not friends with other Silicon Valley engineers or angel investors: You’re not going to have any connections.

And that’s kind how AngelList is designed. It’s all built around connections. So it’s really an insiders game. Now… You don’t have to be like a super-insider; you just have to be someone who’s in Silicon Valley and working as an engineer and have some sort of small social network of friends that are on AngelList. So in that case, you might meet some people and possibly raise money. But if you’re like myself, and you’re outside of Silicon Valley, you don’t have any connections, and you kind of just start cold emailing people— There’s a good chance that you will get blocked banned or suspended from AngelList once you start trying to reach out to investors.

Take my case for instance: I think there’s two reasons why I may have been blocked. Like I said, AngelList’s search functionality is not really very good. And you’ll notice if you try to just look at your connections, or everyone, AngelList’s search results will return tons of people that have just made one angel investment. And maybe that’d be fine if they made the angel investment recently, but you have no idea when they made that one angel investment, it could have been 10 years ago. For example, when searching for angel investors here in Texas the search results returned 16,000 results! or something crazy. How do you sort through all of that to find the real angel investors who are actively searching for deals and investing in companies regularly?

The solution that I found is to use Google. I came up with a pretty good search query that did the trick fairly well:


And then if you want to take it up a notch, you can start adding in the number of deals into your search queries…



And so on and so on, from 1 to 250.

I entered these search queries into Google manually by hand, but it probably would’ve been easier as a bot. Even so, Google actually flagged me as a bot a few times. I had to do the captcha thing to prove I wasn’t a robot. After spending a night doing this research, I discovered some interesting stuff:

I found there are 1,474 investors that have made between one and nine investments.

245 investors that have made 10 to 19 investments.

94 investors have done 20 to 29 investments.

102 investors have done 30 to 49 investments.

90 investors have done 50 to 99 investments.

62 investors have done between 100 and 199 investments.

9 investors have done between 200 and 250 investments.

And there are a few people that have done even more than that!

Now I did not actually compile this list and publish it. I know angel would probably not want me doing that. So it kind of just kept it to myself. But my plan was now that I kind of know how many investors there are, and how many deals they happen to do: Who do I want to target?

I found it was really hard to track time frequency of investment, but total number of investments was kind of the best that I was able to personally figure out. And I wasn’t even able to do it through AngelList’s website. Like I said, I had to do it through Google! So that could be one reason that I got blocked. Maybe AngelList just saw that there was a ton of traffic coming from my computer. I was browsing their site pretty heavily. So maybe CloudFlare maybe like flagged my IP address. So that could be one reason that I got blocked.

I also sent 11 cold messages to investors on the site over two days. So maybe an investor on the site flagged me as a spammer? Whatever the reason… Bam! Blocked! Suspended! Do not pass go. Do not collect angel investment.

I know there’s tons of hype behind AngelList. If you follow the startup world/eco-system it’s easy to get caught up in the hype. You have this feeling like, “Oh, I need to be on AngelList!” But what do you do after signing up and creating a profile? Now what? What do I do? Wait? Well, here’s my recommendation: You don’t need AngelList. AngelList isn’t for you anyway.

But you know what solution there is that IS for you… Crunchbase!

If you haven’t heard of Crunchbase, Crunchbase is website and database created by Mike Harrington of TechCrunch fame. I think it started out as a database of startups. But now also includes a database of investors as well. And they cover all different stages of investments. But what you are going to want to search for, if you have an early stage startup, are investors that are doing pre-seed and seed stage investing.

I’ve had a Crunchbase subscription for a while now, just out of interest, so can kind of see what’s going on. Who’s raising money? Who are the active investors? Etc. etc. But what I was trying to use AngelList for, identifying potential investors, I’ve found you can do really easily on Crunchbase.

So that’s my solution to you if you’ve been blocked, banned, or suspended by AngelList. Just go try Crunchbase instead. It does cost $300 a year. So if you don’t have $300 to spend on something like that, then maybe don’t do it. But if you can spare the $300 I would recommend it.

It’s not a must have. It’s just a tool that’s out there. I’m sure it costs them money to maintain their database. So if you want to check it out, head over to The product is called Crunchbase PRO. The only big difference between Crunchbase and AngelList is that it mainly lists funds, not individual angel investors. But like I said, there are tons of pre-seed and seed stage funds on there investing in the same stage startups as the angel investors over on AngelList.

And one of the cool things is that they’re actually putting in a lot more money than the individual angel investors. They’re not putting in $25,000 checks. They’re doing like $2 million seed deals!

For a company like mine where I don’t have very much traction, I don’t think I’d be able to raise something crazy like $2 million. But there are some funds doing much smaller deals as well. So it’s worth checking out in my opinion even if you aren’t trying to raise seven figures.

Well that’s the end of my rant internet friend. Crunchbase is better than AngelList. The end.


SOLVED: How to fix a DEVELOPER_ERROR when implementing Sign in with Google using @react-native-community/google-signin or expo-google-sign-in

Banging your head against the wall trying to ad Sign in with Google to your React Native application? If the error message you keep running into happens to be DEVELOPER_ERROR, I think I have your fix.

For me, the problem was my build.gradle file for my React Native Android app. The app I happen to be working on has already been published on the Google Play Store, so the production version of the app has been signed using a release version keystore. Apparently I deleted the configuration for the debug version of the app, which did not cause me any problems other than breaking Sign in with Google.

Writing about obscure app configurations can be tough. Does any of what I wrote above make any sense? Probably not! So to make things a little clearer here is what my build.gradle file looked like that did NOT work with Google Social Login:

signingConfigs {
release {
if (project.hasProperty('MYAPP_UPLOAD_STORE_FILE')) {
view raw build.gradle hosted with ❤ by GitHub

And here is the corrected build.gradle file that works with Google Social Login:

signingConfigs {
debug {
storeFile file('debug.keystore')
storePassword 'android'
keyAlias 'androiddebugkey'
keyPassword 'android'
release {
if (project.hasProperty('MYAPP_UPLOAD_STORE_FILE')) {
view raw build.gradle hosted with ❤ by GitHub

I’m sure there are a million different ways you can screw up implementing Sign in with Google, however, if you were able to get Google Social Login to work in a test app, but are having trouble getting it to work in your production app, then this might be your problem.

Also, you need to make sure that you have registered a development and production version of your app in the Google Developer Console. For example, let’s pretend you only have one app registered and it’s working great during development. Then you try to use Sign in with Google in the release version of your app. If you’ve only registered the debug version of your app in the console, Google Social Login isn’t going to work in the release version of your app. So, make sure you register a debug version of your app in the Google Developer Console, and then create a second release version of your app in the Google Developer Console as well. You can pretty much use all of the same code in your app, you will just need to write some logic to toggle between the two different clientIds depending on whether you are running the debug version of your app or the release version of your app.

I know that isn’t very intuitive, or self explanatory, so I’ll clarify: You have to register 2 different applications in the Google Developer Console. While you are developing your app you only need one. But after you go to publish the production version of your app, you will need to register it as a completely different app. Doesn’t make much sense does it? But that’s the way it is!

Last, this blog post really only deals with a rare edge case involving build.gradle. So if you do not find this particular post helpful please follow along with the official react-native-community/google-signin or expo-google-sign-in docs. However, this problem was quite a doozy for me! So hopefully this post will end up helping someone out there.


What is Adaware Secure Search and How do I Remove it from Firefox?

I noticed that the default search engine and homepage in my Firefox web browser recently changed from Google to some super sketch search engine called Adaware Secure Search from a company called Lavasoft. And since you’re reading this blog post on the topic, I assume you are currently running into the same issue and are equally perplexed. Well fret not internet friend! I have your answers right here:

First, to get rid of Adaware just download Malwarebytes from No need to purchase a subscription or anything, just use the free version. Run the scan, and let Malwarebytes do it’s thing.

Second, after running Malwarebytes you’ll discover the source of this Adaware malware garbage: FileZilla! (The FTP Program) Now if you aren’t a user of FileZilla FTP, it’s possible Lavasoft is distributing their malware through other free software in addition to FileZilla. But in my case, FileZilla was the culprit. With that being said, I still really like FileZilla as an FTP client. But it is kind of sad that they’ve resorted to installing crap like that make money.

Third, click on Options -> Home -> Restore Defaults to remove Adware Secure Search from your homepage.

So there you have it! FileZilla is guilty, Malwarebytes has the fix you are looking for, and last make sure to go to Options -> Home and click Restore Defaults to reset your homepage. đź‘Ť


SOLVED: How much do non-skippable in-stream YouTube ads cost on a CPM basis?

Struggling to find some basic estimates on how much your non-skippable in-stream YouTube ads are going to cost on a CPM basis? Finding recent CPM figures can be really tough! This morning I was trying to figure out how much it might cost to run some non-skippable ads on YouTube to promote my new budgeting app, BitBudget, and I was having the hardest time finding any actual figures. Well without further ado, here is the figure I found: $13

If you want to run your ads in the United States targeting 25 – 44 year olds $13 is what Google suggests it’s going to take to submit a competitive bid. How do I know this? Well I was fumbling around in the Google Ads manager and I noticed while trying to create a fake test campaign that a little yellow warning will display inside the manager if you enter too low of a CPM bid. I started at $10, and that’s when I first noticed the little yellow warning. However, after incrementing my bid one dollar at a time the warning dialog disappeared when I got to $13. So there you have it!

If you’re looking to set a competitive CPM bid for the pricier non-skippable variety of YouTube ads, $13 is a good starting point.

Too Low

Just Right
