No matter what I do I cannot get Multi User Editing working in UE5.1. I can set up the server up but my friends is unable to join it. I have made a softether vpn and my friend connected to it. Our unicast ip and port were set to 0.0.0.0:0 and we also tried replacing the zeros (excluding the port) with our actual ipv4. Ive been stuck on this for multiple hours so any help would be fantastic.
