How to debug Client?

As the titles say, how do I debug the client in networking in visual studio.

I’m expecting the GameMode to hit BeginPlay twice but it never happens so I assume that i’m only debugging one process(server), the server process because player controller netword mode is server.

I still want to use single process, I don’t wanna start packing the game for debug purpose.

Please help

I have a question???
The gamemode code is never hit in the client, is it being replicated over the network??
I’m little bit confused .
Where is a good place to store global variables in Unreal Engine for each process?

If you want to know how I debug each process seperatly:

GameMode does not exist on the clients if I recall correctly.
