Timeout when Jellyfin server is behind a CDN

[enigma0Z]

Describe the bug
Cannot see my library on my Cloudflare fronted Jellyfin server with Streamyfin. Vanilla iOS client and web view work fine.

To Reproduce
Steps to reproduce the behavior:

1. Put Jellyfin on a server with nginx reverse proxy in front
2. Point cloudflare at Jellyfin server
3. Point Streamyfin at Cloudflare hostname
4. Cannot connect

Detail
Authentication seems to work. However nothing from the library loads, it’s all blank like it can’t even read the library metadata. No search results either when searching in library.

Local IP works too so it’s gotta be something with how Streamyfin is interacting with the CDN and reverse proxy.

I recently updated my reverse proxy (nginx) to use the SSL hostname header to forward the requests into Jellyfin; iOS client and web view seem to be fine with this, for what it’s worth.

The error itself feels like some kind of time out; I’d be happy to provide detailed logs if there is some way of extracting them out of the app.
