Can't connect to node js TCP server
I am trying to connect to a node js TCP server from another repl, but it is not working (the request just times out)
Raw TCP servers don't work on Replit. You should use something like websockets instead.
A more in-depth explanation:
All repls have the same (public) IP. The HTTP
Host header is used to distinguish between different domains. TCP does not have an equivalent and therefore can't be used, although I have proposed a system with different ports and subdomains.
