I can not say where so problem is located. So I create the bug into CCA. I work with Picard.

Every time I edit/add a cover I get 404 Errors while loading the release in Picard. That caused by requests to archive.org:

Every edit same problem. After 10 hours and more the bahavior is still the same. Covers can't be loaded because of "Not Found" errors.

Here are my edits: https://musicbrainz.org/user/gpol/edits/open

For all edits today I get the 404 error. All (also not approved) edits from yesterday works fine. Other users get the same error: https://community.metabrainz.org/t/red-cd-circle-on-edited-releases-404-for-archive-org-requests/336559/3
