Please help. I am soooo NOOOOOOOOOB!!!

Probably the same issue as described here:

Ideally your Syncthing nodes should be able to establish a direct TCP connection which would give you better performance and would solve the issues with quic.

Did you follow the docs and forward port 22000/tcp on your router?

https://docs.syncthing.net/users/firewall.html#port-forwards

Thank you.

I will make relevant changes to firewall and revert
