Any idea why Lidarr can’t find https://musicbrainz.org/release-group/165b34c9-6132-4632-b1f4-981f51f87235 ? It finds the other four albums but not this one.
It’s the lack of release status. Click the release, then edit, and choose the correct status. It the should show up in Lidarr in a few days.
This is the correct answer, all other comments are just noise lol
Have you tried using the ID (last part of the URL) directly by putting “lidarr:<id>” in the search bar?
Sometimes that helps. Some releases also have some uncommon metadata, causing Lidarr to ignore them, not sure if that’s the case here.
EDIT: I actually think it is the case. If you check your URL page, you notice <unknown> above the release, where the others say “Official”. Lidarr tends to ignore these. This might actually need an edit on Musicbrainz for Lidarr to find it
How long would you expect it to take to propagate? I don’t see it yet, and five days seems like a reasonable time to wait.
