Hello everyone,
I'm having trouble authenticating into my Jellyseerr instance through the Moonfin plugin on my Jellyfin server. I keep getting a red box saying "An unexpected error occurred" during the login process.
My Setup:
Jellyseerr Version: 1.x (Stable) running on http://192.168.0.100:5055
Jellyfin Version: 10.11.6
Plugin: Moonfin (Server-side integration enabled)
Login Method: I have both "Local Sign-In" and "Jellyfin Sign-In" enabled in Jellyseerr settings.
The Issue:
I have a local account in Jellyseerr with my email and password.
In the Moonfin UI, when I try to log in using the "Local Account" tab with my correct email and password, it immediately throws the "An unexpected error occurred" message.
I've also tried the "Jellyfin Account" tab with my Jellyfin credentials, but the error persists.
My Jellyfin server is configured to reach Jellyseerr via http://192.168.0.100:5055 (no trailing slash, no HTTPS as I'm on a local network).
What I've checked:
I can access Jellyseerr perfectly fine via web browser using the same credentials.
"Enable New Jellyfin Sign-In" is checked in Jellyseerr.
The logs in Jellyseerr don't seem to show a failed login attempt, which makes me think the request is being blocked or mangled by the Moonfin SSO Proxy before it reaches the API.
Has anyone encountered this specific error with the Moonfin integration? Any advice on how to debug the communication between the Moonfin Proxy and the Seerr API would be greatly appreciated.
Thank you!
