I think your problem is that 9735 is the p2p protocol port. It’s not a webservice like the grpc rest endpoint (don’t remember that port). I’ve only placed my proxy openresty in front of the grpc rest service.
Yeah, it seems caddy is http only. Trying a ufw rule and IP table entry next to forward all traffic on the port. Will definitely write a guide after figuring it out.
