The problem has been solved. Please close this issue

In new version 1.17.30, SystemAddress::toString outputs UNASSIGNED_ADDRESS no matter using which RakPeer instance, and NetworkIdentifier::toString returns empty string too.

0It was not this case in old versions, and it causes trouble to our blacklist plugins, which can ban specific players according to their client IP.

0This type of ban is so effective, so can you fix this problem or give out other effective ways for client IP address?

I am not able to close by myself
