Additional information:

The domain has be sanitized in the logs.

The logs are only for the failure with <EnableLegacyAuthorization>false</EnableLegacyAuthorization> when I change it to true everything works fine so I didn’t add logs of that.

Nightly and the next release (10.12) will default that option to false and the one after that (10.13) will remove the deprecated methods: [10.12] Default EnableLegacyAuthorization=false breaks Jellyseerr authentication · Issue #15962 · jellyfin/jellyfin · GitHub

Jellyfin auth methods and their deprecation status: Jellyfin API Authorization · GitHub

I would like to keep the legacy/deprecated methods disabled (Yatse is the only thing that is broken for me right now with those disabled), is there any timeline for moving to a non deprecated auth method?
