Thank you very much for the video. I followed it step by step (using a blank project on UE 4.18.3 source), but in the end the dedicated server won’t show up in the Steam internet tab. It’s in the LAN tab and if I don’t use steam I can also join the dedicated server. The steam overlay etc is also showing for the client itself. I have double-checked everything, played around with the ports in all kinds of ways and they seem to work. I also tried it on a second computer without success and to have a client on PC1 join the server on PC2, but I’m not even sure if that works at all with IPs (it was unsuccessful). Really don’t know what else to try, any ideas?
Cheers
