[WINDOWS] Starting a second server instance failed

[Niteruner]

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.

should be fixed now if
usingMultipleServerInstances is set to True in serverSettings.txt
