I’ve been trying to set up a Mumble voice chat server on my home network using a Debian server. As part of the setup process, I need to obtain an SSL certificate from Let’s Encrypt for secure HTTPS access to the server. However, I’m encountering an error when running the Certbot client to request the certificate.
I’ve checked my firewall rules and confirmed that I’ve opened port 80 as required for the Let’s Encrypt verification process. Here’s the relevant rule in my ufw configuration:
80/tcp ALLOW Anywhere
Despite this, I’m still getting the timeout error. Has anyone else encountered this issue before? What steps should I take to troubleshoot further?
Since this is on a home network, have you also forwarded port 80 from your router to your machine running certbot?
This is one of the reasons I use the DNS challenge instead… Then you don’t have to route all these Let’s Encrypt challenges into your internal network.

Maybe…? I’m not familiar with that router software, but it looks plausible to me…
