Shuffle randomly stops

[myjunkmalebox 10]

I recently migrated from windows server to Linux server.  Then went well.  I frequently leave a play list on shuffle running through the android app over night.  
Before the migration it would stop playing less than once a month.  Now on the Linux server it stops several times a week.  Not every night.  Frequently when the phone is checked it's just sitting on the play list screen.  Some times the screen is off and the app has to be opened.  I've tired clearing the cache on the phone, but that did not help.  

I'll also note: The linux version doesn't seem as responsive on app open.  I've never seen "connecting to server" before.  After the migration I see it from time to time.  The new linux server is hosted in a k3s node, the pod has no resources restrictions.  The new server hardware is a significant upgrade from the previous server.  Reviewing resource usage over night show the server required less than 1% requested cpu, and less than 80% requested RAM all night.  

Any idea what else I can try?
