I wanted to mention that I referred to this thread in another ( Need a TCP Listener that works on 4.19 - C++ Gameplay Programming - Unreal Engine Forums ).
If anybody has a TCP Listener that 1. works in 4.19 and perhaps 2. Run on its own thread I would like to see the code. I have not been able to get any of the pieces of code working that were shared in this thread. Makes me wonder how things will go in 4.20 with all the changes.
