If you choose this third approach, the server will always use a port number one higher than the one you set. This ensures that there won't be a conflict between the Editor and the server when they run on the same machine. When you configure the static endpoint for your other Unreal Editor instances in the following section, you will need to remember to add one to the port number you set in the Project Settings. For example, if you set 50000 as the port number for the unicast endpoint in the Editor that you use to launch the server, you will need to configure other instances of the Editor to connect to the static endpoint with port 50001.
