No servers found

I’ve installed Plex for Xbox 360 and I’ve got Plex Media Server 0.9.12.11 running on a local PC. My smart tv connects to the server just fine. But Xbox 360 keeps repeating “No servers found”

Windows firewall has been opened for Plex. No other applications are running on the PC. I’ve tried signing out both server an xbox app and signing back in again. The pin sign in works just fine, but it refuses to find the server.

Anybody any ideas on how to fix this? Thanks in advance.

Solved it. Needed to log in with the the server under server settings as well. Weird having to logins in one app for the same account.
