Hi dear dynamic Unreal community,
I have developed my own TCP and UDP socvkets (with C++) in a UE plugin and I use them inside Blueprint to communicate with an external robot.
The TCP server runs in my Unreal blueprint and a client connects to it from outside.
When I run it within the Editor, everything runs well. I get the data properly.
When I package the game, it becomes impossible to establish the TCP connection from the client to the packaged game.
I am using UE 4.18.
It seems like those protocols are being blocked by Unreal.
I tried disabling TCP and UDP messaging servbices, but then I get a “Fatal error” when starting the packaged game.
Also, I have disabled all antivirus and firewall options to make sure it is not a security issue.
I have tried TCP ports 1024 and 8888.
Is there anything I should do or disable inside Unreal before to package my game ?
Any advice would be greatly appreciated !
Thanks and regards,
