Windows App Connection Failure

[Build]

Windows App Version: 1.9.1 (Windows 11/Chocolatey)
Android  App Version: 2.5.2 (F-Droid)
Server Version: 10.8.10 (Docker w/ Traefik/Cloudflare/LetsEncrypt)

The issue I am encountering is that the Windows Jellyfin client will not connect (Connection Failure - We're unable to connect to the selected server right now). I had the same problem with my android client until after I uninstalled the google play version and installed from the f-droid repos. The connection fails silently with no logs on the server. I never had any issues connecting from web clients (Firefox) or Finamp.

The issue started to occur after I introduced cloudflare and its proxy/certificate handling into the mix, so certificate shenanigans are suspect. Through digging almost all day, I'm not much closer to resolving it on my windows client, and I'd call my android fix a bandaid if anything. SSL Labs doesn't seem to show anything currently wrong with my domain. I've attempted to remove all local data from my Windows Jellyfin client (~\AppData\Local) but reinstalls do not fix it.

Is there a cert/hostname mismatch with that cloud flare proxy in between? Do you have to provide the cloud flare proxy with that cert? Not sure how that works since I run my reverse proxy on the same machine.

Also, FYI, pretty sure this is against cloud flare's TOS. Never heard of anyone's account being terminated, just wanted to put that out there.

Good to know. I've disabled the proxy to the subdomain, issue remains identical. Not sure about a mismatch occuring.

Can you still get to jellyfin directly on port 8096?

[Build]

No. With my traefik configuration all my services are consolidated through 443 (mandatory SSL) so I don't believe I can connect with IP:Port regardless of client.

[Build]

Adjusted config to allow local ips to connect via IP:Port, which works on the Windows client.
