"Failed to connect via relay server: Failed to connect to relay server: Please try later"

[Californian]

I'm trying to use my tablet as an external display. I came across rustdesk because Gnome's remote desktop feature doesn't seem to work, and deskreen was too tedious with the QR code every time. I don't have anything too crazy complex going on: simple home network (Nest Pro router/APs), static IP for my computer. I'm very experienced with docker-compose so I'm using that for my server.

It's possible my docker-compose.yml file is wrong, since I used the one from the repo instead of the docs (the compose yaml in the docs don't expose ports, so I assume those are just wrong and need fixing).

I'm on arch linux. I installed the rustdesk-bin package, ran it with sudo, changed the server settings to localhost/localhost and left the API server blank. It says "Ready" on the bottom.

On my tablet, I've installed the rustdesk app. I changed the server settings to my computer's local IP (192.168...) for relay and ID servers. My computer is definitely receiving a connection, since the docker compose logs show "New relay request" once it fails to connect (in the app it fails with the message "Failed to connect via relay server: Failed to connect to relay server: Please try later").

Is there something I'm missing here? Love the project conceptually and I'm excited for the potential here, really hoping I can get this to work! Thanks in advance 🙂
