When starting a second instance of the dedicated server, I am getting the following error;
UNASSIGNED_SYSTEM_ADDRESS
37.120.xxx.xxx (IP Adress redacted)
Starting dedicated server.

The client and server Ports differ from the first instance, I also tried it with defferent users.
It seems, that the server only checks the IP, not the port, so only one instance is possible with the same IP.
