I recently joined and made my first edit, adding a release (Keep Believing) for the band Truth. I see it on the musicbrainz site but it has been about 2 days and it hasn’t shown up in lidarr. Even searching in lidarr by the release group id doesn’t find it.
How do I know whether it just needs more time or if I did something wrong and need to correct it? Since this was my first edit I’m betting I left out some piece of information but there are no errors/warnings that I have found.
AFAIK lidarr is running on their own replicated database copy of MusicBrainz. Maybe it gets synced more infrequently, or there is some issue with the sync currently? The lidarr team would know.
From AI:
"
Lidarr’s search function was not working due to a broken, third-party MusicBrainz metadata server, which has since been addressed with a rebuilt server and caching mechanism. You can now try to get Lidarr working by switching to a develop version, restarting, and adding api.musicinfo.pro under Metadata > Custom Lidarr if you are on an older version of Lidarr. You may need to hit “Refresh Artists” on your existing library or add new artists to help populate the new cache.
What to Do:
Update to the latest version of Lidarr, preferably the develop branch, as these versions have improved metadata server communication.
Restart Lidarr after updating.
If on a previous version, add api.musicinfo.pro under Metadata > Custom Lidarr.
Refresh your library and add new artists to help populate the updated cache.
Use the develop version of the Lidarr application, as it includes changes that can help with artist and album lookups.
Why it wasn’t working:
Metadata Server Failure:Lidarr relies on third-party services like the MusicBrainz metadata server, which failed due to a schema change and a subsequent attempt at a repair that did not work.
Caching and Server Overload:Because of the failure and the limited time the development team has, the new metadata server is being rebuilt, and the initial search errors you experienced were expected as the cache was populated, according to a Reddit post on August 18, 2025.
Important Considerations:
Wait for the cache to fill:You may still see some errors as the cache for the new metadata server continues to build.
New libraries and Spotify lists:New Lidarr libraries or Spotify list additions are not ready and will require waiting for the new server to be fully rebuilt.
No workaround for the old metadata server:There is no workaround to resolve this issue yourself, and attempting to bypass the metadata server in any way is a violation of the Lidarr community rules.

I just ran a quick test:
Created a new docker container with the mentioned alternative image blampe:lidarr.
This alternative image was created to include a little nginx proxy that redirects the broken (and hardcoded! ) API url to the currently working api.musicinfo.pro URL.
I have not fully tested this container and I have not migrated my existing database!
This was only a test to search for the above “Truth” where I get now a long list of results, including
