Originally created by @bannert1337 on GitHub (Mar 21, 2025).

After I switched FreshRSS from Cloudflare Tunnel to Pangolin, authentication with Authenik wouldn't work anymore with the error:

Image

This happens because the HTTP headers are not or incorrectly forwarded.

It looks like Traefik is passing the host header along by default: https://doc.traefik.io/traefik/routing/services/#pass-host-header

Here is an excerpt I just tested using the whoami container.
