2 simultaneous TCP connections at same time fails while more than 2 works

Thank you @zieckey building this simple to use and concise networking library. I'm having a weird issue but this only happen with constant two (2) simultaneous TCP connections. The two (2) simultaneous TCP connections get closed automatically.

I don't know the reason, but it appear this doesn't happen with 1 TCP connection or more than 2 (eg 4, 5, 6, 7, 8 ....) simultaneous TCP connections.

This is really a big issue for me. Can anyone investigate why this happen?

Turns out that it's a firewall issue.
