Problem with Metabrainz/Musicbrainz & Temp Bans

[Zauberwaldi 5]

Hi all,

dont know if this is the right Place.

Yesterday i experienced alot of timeouts/not loading on the Musicbrainz Page.

I wrote and email to the Support because on mobile it worked.

Turns out i was temp banned and it might have to do with the new problem that Metabrainz have with Bots.

They changed something and that now leads to temp bans.

Via support mail i got the following links:

 

https://blog.metabrainz.org/2026/08/24/blocked-listenbrainz-services-user-agent-strings/

and the open issue for jellifyn

https://github.com/lyarenei/jellyfin-plugin-listenbrainz/issues/179

 

maybe this helps to fix the problem.

I only use Emby (4.9.5.0 windows) with the Listenbrainz & Last.FM Plugin, that might cause the Problem

Something is calling the LB API with a completely undefined user agent. One thing we've seen does that is the LB plugin for Jellyfin (which should be fixed in the latest version, so if you are using that an update might be all you need), but there might be other potential sources."

 

 

thats what i got for my question if i am banned.

Dont know if this is the right place for it, if not, please let me know where to post this.

Thanks
