Hi there,

I’m also getting the No Music Servers error. It sure would be nice to be able to move the music player window when this error is displayed…

Anywho, relevant logs:

https://plex.xxxxxxxx.xxxx does actually work, if a little slowly, it’s a UK residential ADSL connection with only ~1MB upload going via Cloudflare.

Let me know what further troubleshooting I can do to diagnose this issue. Or if it’s possible to length the timeouts.

Cheers,

Steve

this perhaps?

Cheers, I did see that, I should have noted that there was no mention of certificate errors in the logs, and no matching log lines similar to those in that post.
I suppose Plex could be checking to see if the FQDN matches the server name subject in the certificate and forgetting to check the SAN, but that’s be out of the ordinary.

@stedaniels ~ I suspect we’re doing something too simplistic there; can you DM me with exact details about the cert? Should be easy to fix…

The “server name isn’t valid, ignoring” error is from the cert checking code. I think you may have nailed the cause, we’re doing:

servername !== cert.subject.CN

which apparently isn’t enough :sweat_smile:
