I am unable to connect to the tcp domain and port for my grpc service on railway

I deployed my grpc service built in Go on railway but when i try to connect to the tcp port ballast.proxy.rlwy.net:32026, it shows service unavailable. I've been on this issue for hours. The grpc service works fine in development. I can call my service using localhost:6000 and it works but on railway the provided tcp domain and port does not work.

What could be the issue? can anyone help?

Hello,

Are you listening on IPv4?

So listening on ipv6 causes these kinds of errors?

Its likely yes, please try IPv4 only.

wow! it worked! I explicitly changed "tcp" to "tcp4": 

listener, err := net.Listen("tcp4", config.GRPCServerAddress)
	if err != nil {
		log.Fatal("cannot create listener:", err)
	}
