After spotify blocked my account (enforcement of password reset) due to "suspicious login activity" I received a mail from listenbrainz telling me, that the connection to spotify was interrupted.

I tried to re-establish the connection after my spotify account was recovered - but the workflow to connect spotify ended with following error message:

internal server error
