Unable to play Library Radio

Amp: 3.4.1
Server: 1.21.1.3876

I’d like to report that I’m (maybe we) still unable to play most of the library radios. For some odd reason, the only one that I don’t have trouble with is “Randon Album Radio”. That one plays ok.
I enabled debug and trace logs but, nothing is said on the server-side, so I’m attaching my cellphone logs and a screenshot of the error I’m getting:

Please enabled debug logging on your server; disable verbose logging; try playing some radios, and then attach your server logs. There should be something in there, it doesn’t make sense that we’d see this error w/o server being involved.

Thanks for answering. Here are the logs. I played some random tracks first and then I tried to play like 6 different Library Radios:

You’ll need to enable DEBUG logging (but not verbose) and redo the server logs.

Sorry Elan, I had it enabled in settings > debug, when the correct location was settings > general. Confusing.

So again, I played some individual tracks (always work), then some Radios that failed, and at last the only one that seems to work “Random Album Radio”.

OK, so seeing this:

Jan 21, 2021 08:31:14.989 [0x7f39b7fff700] DEBUG - Radio: Generated library decade mode with 3 top tracks per album in 3 ms into 0 tracks.

The likeliest reason for this is that you’ve disabled popularity here:

Yes, I didn’t have this option checked. I enabled it, scanned my library a couple of times, and waited for about 12 hours, just in case some background task had to be done, but still, no progress.
Here are the new logs:

Scanning won’t help. Refresh Metadata is needed.

That did the trick!

I thought Load popular track data, which powers radio stations and the popular tracks area was related to popular tracks at the current year, which I have no interest.
Enabling that option and doing a full metadata refresh got all the Radios working.

If I may, I would like to suggest a more intuitive message in the mobile app, like “To listen to radios, first enable … on plex server”. On the server-side, once that option is enabled, it should trigger a full refresh automatically.

Thanks, @elan, and @OttoKerner
