If i try to run a extra client for multiplayer testing host is fine but client is just a black screen. When i use a dedicated server client is also a black screen.
Hi Zeldhoron,
Is this happening during PIE, or in a packaged game? Are you testing on a single computer or multiple machines?
I’d also like to take a look at your project log, with a few extra settings. In your project’s Config folder, please open DefaultEngine.ini and add following:
[Core.Log]
LogNet=verbose
LogOnline=verbose
Run game with multiplayer and then and attach log from your project folder (\Saved\Logs). Thanks!
I wasn’t able to test it on another computer yet but this is happening during PIE.

Does this occur in a new project, or only your current project?
Also, take a look at this answer to see if it may solve issue for you:
Also in new projects, and no i don’t have that ethernet card.
BTW, i do have bitdefender which caused me some problems in past, perhaps that’s what’s causing problem, but idk how to solve that (disabling it doesn’t resolve it but it hasn’t older problems either so yeah)
Hi Zeldhoron,
Thanks for providing logs - it looks like server instance is listening for connections on port 7779, but client instance is trying to connect to port 7777. You may have another instance of an Unreal server, or another application, that bound to port 7777 first. In Windows, you can use a command like netstat -ab -p UDP to see which programs are using specific UDP ports.
Try closing any other applications that bind port 7777 before starting a PIE session for your project. If this isn’t possible or desirable, you can also change default port that Unreal uses by adding a Port entry to your DefaultEngine.ini file:
[URL]
Port=<unique port number>
But use a number other than 7777 that’s unlikely to be used by other programs.
Yes, netgear genie was using ports 7777 and 7778, i uninstalled it since i actually don"t use it, thx for help
