First, this post is more for me as a reminder should I have this problem again. But, if it helps you resolve your problem, yea!
Problem (tl;dr version): Certbot didn’t update the ssl certificates on one of my servers, resulting in ugly messages about the websites not being safe.
Long Version: I’m hosting my own sites on Amazon EC2 servers running AMI flavor of Linux. About a year ago I upgraded from standard webpages to ssl to make Google and other search engines happy. Everything was going fine until recently when the site didn’t renew the certificates for SSL from Let’s Encrypt.
While I had followed the Amazon tutorial exactly (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/SSL-on-an-instance.html#letsencrypt) Certbot wasn’t running any longer. After troubleshooting, I found that it was a common problem with the latest versions of certbot. There were a lot of solutions provided by various people, none worked correctly. What did work is:
On the github website (https://github.com/certbot/certbot/issues/1680#issuecomment-358728515) I found a solution that worked:
sudo rm -rf /opt/eff.org/*
sudo pip install -U certbot
sudo certbot renew –-debug
I did have to make one change:
sudo ./certbot-auto renew –-debug
Now the solutions is saved should I (or anyone else) need it!

We are […]
We made the decision to wait for #AmazonLumberyard 1.10 before we release “Game Development Fundamentals with Amazon Lumberyard”. The textbook is 90% complete. We want to make sure everything is accurate for the new features expected in the next release. The great people at @AmznLumberyard have ave 6 to 8 weeks between releases, so 1.10 […]
Why Deep Learning? Several months ago one of my former students, Dr. Julia S. Slige, began posting a series of tutorials on using R for data mining. Julia even has a book on the topic published by O’Reilly. Her posts and subsequent research got me to thinking about Deep Learning, a key part of my […]
Game Development Fundamentals with Amazon Lumberyard will available soon! Early this year we provided an early release copy of the textbook to a small group of students. We received some very valuable feedback on how to make the textbook even better, especially in how we approach teaching Blender. As we were completing the changes, Dr. […]
