Cannot connect on Android TV - But works on everything else

[nothingveryobvious]

Describe the problem

1. 3 users on 3 different networks, separate from my own network
2. Can connect to https://jellyfin.mydomain.com on Jellyfin iOS, Jellyfin on a web browser (phone and computer), Jellyfin Media Player
3. Can connect to https://jellyfin.mydomain.com in a web browser on Google TV
4. Can connect to https://jellyfin.mydomain.com in Streamyfin Alpha on Google TV
4. CANNOT connect to https://jellyfin.mydomain.com on Jellyfin Android TV (or Dune) on Google TV
5. Interestingly, if already connected, everything is fine. But if you forget the server and try to reconnect, it doesn't work. This is probably why we never noticed this issue before, until a new user was getting set up.

The error that appears is:

Unable to connect to server, tried the following addresses:
https://jellyfin.mydomain.com - Connection timed out
https://jellyfin.mydomain.com:8096 - Connection timed out
https://jellyfin.mydomain.com:8920 - Connection timed out


Logs

These are the logs for one of the Google TVs while trying to connect to the server.

Application version

0.18.11

Where did you install the app from?

Google TV Store

Device information

TCL 2024 4K TV 75" with Google TV

Issue is occurring on 3 Google TVs.

Android version

Android 12

Jellyfin server version

10.10.7 natively on Mac

Other context

Reverse proxy is SWAG using Cloudflare (proxy disabled; DNS only) with SSL set to Full (Strict). I haven't touched anything on Cloudflare since I set it up years ago. I update the SWAG config for Jellyfin (using the stock config) every once in a while.

I tried switching to NGINX Proxy Manager, still using Cloudflare (DNS only), but the error is still just as described.

I cannot try this without Cloudflare because I don't have a public IP.

From the reading the logs, I visited https://jellyfin.mydomain.com/System/Info/Public on my computer and I get the following:


{"LocalAddress":"http://<local-ip>:8096","ServerName":"server-name-here","Version":"10.10.7","ProductName":"Jellyfin Server","OperatingSystem":"","Id":"number-here","StartupWizardCompleted":true}

I've confirmed with openssl that it's TLS 1.3:

Protocol  : TLSv1.3

I can provide my SSL Labs Report, but essentially it received an A rating.

These are my results with SSL Hopper:



I have not tested this on another Android TV device, like an Amazon FireStick. I'm afraid if I disconnect and forget the server, I won't be able to connect again.


I'd really appreciate some help with this; this is driving me crazy. Thank you!
