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?
Sounds like you have nothing listening on port 80 that resolves for your domain for Let’sEncrypt to verify that you own the domain. You need a webserver listening on port 80 and that Certbot can access if you’re using the http method.
Basically you’re forwarding traffic to port 80 but there’s nothing on port 80.
