I ended up getting it to work. Here's the config for NPM if anyone in the future needs it!

Hm. Where do you see the error about it being missing? Try the whoami image and verify which headers are being passed. Even though it’s called Cookie, it’s actually a header :)

You telling me it's actually a header saved the day ^^

Did anyone else have any issues after upgrading to Authentik version 2025.10.0? This doesn't seem to work at all anymore.

Good to know. Holding off on the upgrade.

I have stopped using this some time ago (switched to Jellyseerr). If you figure out what's wrong - let me know and I'll update the snippet.

Does jellyseerr have better support for SSO or why did you end up not using this anymore?

It does. There is a PR (not yet merged) that adds a proper OIDC support. Even though it is not merged - the preview image built with it works just fine.

The image in question:

docker.io/fallenbagel/jellyseerr:preview-OIDC

P.S. I’ve also moved away from Plex to Jellyfin.
