FPSSample - reduced to just Chat - Problem with recieving events

Hello everyone!

I tried to reduce the FPSSample to the bare minimum but I'm having problems recieving events or more precise the chat events.

Connecting from client to server works.
Server has a proper list of clients and recieves chat events and sends them to the connected clients.
Clients never recieve it though and I'm just getting OnData with 7-8 byte packages but never any with a chat msg.
I thought there was some channel thingy going on but I'm not seeing it why the messages are never recieved.

I guess I'm something missing and if it's obvious for someone I'd appreciate to know what I'm doing wrong.
In this build I also have another bug that was working before, that clients can't send their name anymore. It's empty and it has something to do with adding the PlayerSystems that I haven't added before.
I can't pinpoint the cause of this either.

To test the build.
On one of the instances, open console with F1 and type 'serve' and/or 'client'
Sending broadcasts works on server with just command 'c'.
On client, pressing enter opens the chat window.

Thanks and greetings,
Thomas
