SOLVED: NGINX Proxy Manager not working with jellyfin

[tee]

Hello,
im working on getting jellyfin working and i want to get nginx proxy manager working so that when i go to jellyfin.mydomain.blabla. In this screenshot      you can see that i get to the site but i cannot get to the login screen and when i try to click connect i get this error. If i connect direct via the ip address it works perfectly fine. Both the NPM and Jellyfin run on my truenas scale system in docker. Here is my NPM configuration              . Please let me know if you need more information.
