Would need logs to start an investigation of the issues you still have on PMS 1.22.0.4163
Please run with debug logging enabled - see https://support.plex.tv/articles/201643703-reporting-issues-with-plex-media-server/
With debug logging already enabled, please restart the server to make sure we get fresh logs set created.
When the problem arises - note down the time and capture the logs zip
and attach with details when the issue arose and when was last successful tune
For logs download - see https://support.plex.tv/articles/200250417-plex-media-server-log-files/
Thanks
