Describe the Bug

I have Multi-scrobbler working fine across all devices with Plex. I noticed that sometimes the Plex task on the web front end for multiscrobbler would go idle. After testing further, it happens whenever I play a Plex Live TV stream with my OTA antenna. If I start a stream, the Plex task in Multiscrobbler goes idle and then when stopping the stream it returns to running status. However if I am watching a long program, the retry time keeps compounding so it becomes multiple minutes or more between attemped relaunches.

I have tried to block libraries that aren't music related, allow only libraries that are music related, blocking sectionTypes, ignore missing is set to true. The only way I have prevented it is by blocking a device as a whole. This doesn't work as a solution for me unfortunately since I use other devices to play Live TV that I also play music on.

I included one section of the log which is what repeats and the restarting polling time seems to double every time.

When I block the device as a whole, this is how it registers in the log
[2025-11-29 01:52:46.583 -0500] WARN : [App] [Sources] [Plex - NastyNAS] Player State for -> 17B01E82-F-Plex for Apple TV-Apple TV-MY_PLEX_USERNAME-Session376 News 4 NY at 11 - News 4 NY at 11 <-- is being dropped because 'devicesBlock includes a phrase found in 17B01E82-F-Plex for Apple TV-Apple TV

Let me know if there is any other information I can provide to troubleshoot.

Thanks for the detailed report.

I've implemented a fix for this that should resolve the error you are seeing. Please try docker image foxxmd/multi-scrobbler:edge and let me know if that works. You can remove the device block.

Hi FoxxMD,

Confirming that this has fixed the problems I was experiencing. I removed all the device and type blocks and from the debug log the feed is being ignored because it doesn't fall under my Music library which is the only one I set to be tracked so this 100% good for me. Thank you for your help and let me know if you need to test anything additional.
