So I’m setting up secure domain following the instructions here. I completed everything and double checked the configs. However, when I go to guest.[mydomain], I get a can’t connect to server error (“Hmm. We’re having trouble finding that site.” on Firefox). I already tried restarting the server and updating Prosody, but neither worked. What am I doing wrong? According to the setup guide, I shouldn’t have to do any DNS config for this to work.
