various methods for playing on Apple TV

[spool]

Hello, thank you for reading my post.

I am running a Jellyfin server on my local network. It is set to require HTTPS and uses a self-signed certificate. It runs on the same VLAN as my client devices (phone, laptop, Apple TV).

I can connect without issue from my phone or laptop via browser. I can Airplay Jellyfin from my phone to my laptop.

I cannot connect from my Apple TV. I have tried:
- adding the self-signed certificate to the TV's profiles
- Swiftfin, fails immediately after trying to connect
- Infuse, fails immediately after trying to connect
- Airplay, shows a black screen with a red icon in the bottom left. I can Airplay non-Jellyfin media to the TV without issue.
- activating "HEVC" and "AV1" in "Encoding format options"

In all cases, the Jellyfin log shows no activity.

Any suggestions? Thanks.
