On August 21, my Yunohost server, which I keep in my house, started warning we that port 80 was inaccessible from the Internet. None of my sites use port 80, so everything kept working, but I was concerned because I knew that my Let’s Encrypt certificate would fail to automatically renew if I didn’t fix the problem. Canyouseeme.org confirmed that the port was inaccessible. Today, with this evening’s diagnostic report, my server’s warning was gone and Canyouseeme.org confirms that the port is accessible again. I’m pleasantly surprised, but baffled.
Has anyone else run into a similar problem? I am on a residential FiOS connection.
As an aside, if you use DNS challenge you don’t even need port 80 open at all for your certificates to be verified.
Yes, I was going to attempt it this week, but hopefully I’m in the clear. With Yunohost the http challenge for renewal is done automatically, but apparently the DNS challenge is a manual process. It wouldn’t be the end of the world, but I just like having nice things.
It’s not an ideal solution, but this guy did the renewal using certbot and just linked the certificate into yunohost for DNS renewal.
