Client won't join to the local server

[NightlyColt]

I don’t know why, but after installing Hammachi, my computer won’t even join my local server that I ran with the command: “C:\Program Files\Epic Games\UE_5.1\Engine\Binaries\Win64\UnrealEditor.exe” “D:\Projects\Unreal\Battle_Roam\Battle_Roam.uproject” /Game/ThirdPerson/Maps/ThirdPersonMap?listen -server -log

Then I ran this command for the client: “C:\Program Files\Epic Games\UE_5.1\Engine\Binaries\Win64\UnrealEditor.exe” “D:\Projects\Unreal\Battle_Roam\Battle_Roam.uproject” 127.0.0.1:7777 -game -log

It used to be able to connect but now I get this error:

Does anyone know how I can debug this or maybe a probable cause of this?

If it worked before but does not work now then that suggests you have a problem with the code changes. Review the end of lecture code. Even the most minute difference can cause a problem.

Let me know how you get on.
