PlexAmp wont play, multiple devices

Server Version#: 1.42.2.10156
Player Version#: iOS - 4.12.4

Hello all, I am unsure where to turn to resolve an ongoing issues I have been having with PlexAmp. I have a large library of music and like to shuffle through all music randomly when listening to music. When I look in the library tab in PlexAmp I see all tracks but when clicking on the track or “all music” playlist I get “Unable to load data. This makes me sad.”

I have done the following:

Re-scanned folders

Removed the folder from Plex and re-add the folder

Uninstall Plex server and reinstall

Any suggestions on where I can turn to further troubleshoot this issue?

Edit: added pic of what I see in plex.

It doesn’t look like you’re seeing music in Plex web either?

You haven’t posted Plexamp logs but I would suspect there’s potentially some corrupt data in the database (invalid UTF-8, e.g.)

Thanks for the reply. I have attached logs. I reloaded music (again) in plex and in plexamp (iOS) I am getting a spinning wheel when going to play all music. Unsure where to turn now.

Edit: attach what I see in iOS (multiple devices)

It looks like the server isn’t returning anything:

Looks like an empty list.

Seeing some other weird stuff too like:

Is there something between Plexamp and the server, networkalogically?

My setup is pretty standard and the iOS devices were working before, unsure what changed. I have modem > switch > WiFi router.

But after doing some more troubleshooting I found that hardwired devices (windows) will work normally, so it is only WiFi devices having this issue. I will have to troubleshoot my network further and see what I find. I am open to any suggestions.

Also, Plex video seems to be working normally both on LAN and WAN.

Thank you so far for all the help.

To clarify, Plexamp works fine on desktop/wired, but fails on desktop/WiFi?

Just did some testing and strangely enough music works through the Plex app on windows PC with WiFi. It is only mobile devices having an issue playing. On mobile devices I get the above screen with a spinning circle.

What about Plexamp on Windows PC?

Yes, Plexamp on Window PC over LAN works.

I don’t think you can have a switch to a modem. If this works, your modem is also a router so you are on 2 separate networks. Change your router to work as an access hub.
