plugin skips songs in longer playlists

[ElFishi]

When I play a long playlist LMS stops playing after 10 to 20 songs.
When I click on Play now, most following entries in the playlist are skipped with
[25-05-08 06:43:10.1121] Plugins::YouTube::M4a::__ANON__ (147) could not find get properties 403 Forbidden
After that only very few entries in the list are playing and then only for seconds.

Strangely, the problem goes away over night. I play youtube playlists in the morning for a while without a problem. After some 10-20 songs the skipping begins. I stop using Youtube and try again in the next morning and the plugin works until it fails again for the day.

Also restarting LMS seems to reset the problem. After restart I can play a few songs again before the playlist trips.

Attached is a Debug-logfile after a restart. The playlist stalled after four songs and I pressed play again.

I clipped the log after the first few 403 messages, but it went on for a lot more.

Same issue—it started about a week ago.
The server had been running flawlessly before that, and nothing in the runtime environment has changed.

Only #short videos in the list can be played; all others trigger a 403 error.

Once triggered, I have to wait for a random period before it recovers.

I’ve reinstalled the latest release of Lyrion Music Server, recreated the YouTube project, and reapplied the OAuth ID and API key, but the issue remains unresolved.

Same issue
Unable to figure out that when and why the songs are getting skipped.
The follwoing line from the log:
[25-05-14 16:43:10.1121] Plugins::YouTube::M4a::ANON (147) could not find get properties 403 Forbidden
I have tried reinstalling the plugin and even tried reappling the OAuth ID and API key. But the issue remains same.
