Send excape packet to server and then block reconnect afterwards. you will get server nexus ip either in reconnect packet iself or in client.state.ConTargetIp (forgot how its called correctly, because i use my own proxy). Then compare that ip to list of server which you can get from realmofthemadgod.appspo*****m/char/list or if its cached in krelay itself ( dont know either, because i use my own proxy )
