Hi,

I tried to import listens from a CSV file on https://listenbrainz.org/settings/import/, selecting Libre.fm as the source of the file.

Steps:
1. Go to https://listenbrainz.org/settings/import/ while logged in
2. Select the CSV file and choose Libre.fm as the source
3. Start the import

Result: as soon as the page loads, I get "There was an error retrieving your imports in progress". When I start the import, I get "There was an error creating an import of your data". Both say "TypeError: NetworkError when attempting to fetch resource."

In the Firefox network tab, the OPTIONS preflight to api.listenbrainz.org/1/import-listens/ and /1/import-listens/list/ returns 404, so the browser cancels the actual requests. The rest of the site loads fine.

Same result with curl from a server, no browser or extensions involved:

curl -i -X OPTIONS https://api.listenbrainz.org/1/import-listens/list/ -H "Origin: https://listenbrainz.org" -H "Access-Control-Request-Method: GET" -H "Access-Control-Request-Headers: authorization"

HTTP/2 404

{"code":404,"error":"The requested URL was not found on the server. ..."}

Tested today (2026-10-14) around 07:49 UTC.
