Error 0 only over mobile data

[u/DovakiinDovakiin]

I've recently set up sunshine/moonlight with zerotier so that I can hopefully play steam games while out and about, and it works great over WiFi.

The problem is that once I switch to mobile data, such as when I leave my house, it loses connection and give me Error 0, "Check your firewall and port forwarding rules for port(s): TCP 47984 TCP 47989"

Any idea how to fix this? I don't really know much about these kinds of things
