Unreal Networking and multiplayer (Using Hamachi on LAN). Error when joining by cli with IPv4

I’ve been experiencing an error I haven’t been able to resolve for about a week, after getting into the GameDev.tv course on Unreal Engine 4 networking.
If anyone could provide some insight I’d be grateful. screenshots below.


  • I setup logmein Hamachi computer A, copy the ipv4 address of computer A, then start the server on computer A.

  • I start LogMeIn Hamachi computer B, Join Computer A’s server.

  • I use this command to join Computer A’s game instance

  • “C:\Program Files\Epic Games\UE_4.23\Engine\Binaries\Win64\UE4Editor.exe” “E:\Unreal\LearningUnrealNetworking\NetworkingProj\MyProject3.uproject” {IP} -game -log
