If you are using Lidarr and experiencing problems with MusicBrainz metadata searches and imports in Lidarr, please read on:
This impacts all searches and imports. On 5/21, Musicbrainz pushed a schema change which broke our metadata server. The devs attempted a repair using MB’s scripts, and those failed to work. The devs are currently working on a rebuild of the metadata server, but they are very short on personal time to devote to this, and it will be up when they are able to get to it.
Occasionally searches work but not adding, this is just cloudflare still having it in cache and is not a sign it’s coming back up.
We have no ETA, nor can we provide one. There is nothing you can do to resolve this, there are no workarounds. You cannot add artists to Lidarr through any alternate method.
Please continue to use this Lidarr channel for support questions only. This discord is for support and discussion of official builds, and any discussion of how to get around Lidarr’s metadata server in any way is off topic. Thank you for your continued patience.
