As long as you get something from your backend, I don't see anything could
be wrong on the proxy. Backend get the connection, that's all.

I guess it was because your backend get frustrated for all incoming
requests being from frontend. HTTP proxy can pass client IP info by
"X-Forwarded-For". That doesn't work for TCP proxy.

For testing, I suggest you to start with some basic http service on your
backend.
