Update – I’ve been told its MGS that is blocking these on login. So nothing we can actually do from our end. I’ve asked the guys to contact MGS to see if anything can be done…
Otherwise, tell your players to disable their internet connection and then enable it again.. The modem/router *should* allocate a new IP (unless they are on a static address of course) and that should fix the problem. Unless of course they are allocated another IP in a banned state..
