I just set up Syncthing with the instructions I found at How to Install Syncthing on Ubuntu Desktop/Server
I also have Caddy v2 running via Docker-Compose. The portion for Syncthing is:
sync.domain.me {
reverse_proxy http://localhost:8384
}
However, when I try to access Syncthing through my domain, it returns with error 502.
Looking at the logs of Caddy, I see
