add some information and documentation ...
The server mentioned in the thread is a VIP GOLD (Type 3) [CODE 26] and it shares the event server with the VIP PLATINUM (Type 4) [CODE 27]
Server Event code: [CODE 36]
In the event server (IGC.GameServer_M) the document VipSettings.xml
<VipSystem LevelType="3" SendRatesChangeMessage="1">
MapServerInfo.xml
When the new server came up [CODE 28] I made it connect to the event server of the FREE servers [CODE 32]. Realizing the error 2 days later connect VIP GOLD server [CODE 28] to VIP event server [CODE 36]. When the server was up, the disconnection error began to appear again
In short: When TYPE 3 and TYPE 4 servers share the event server, this error occurs. But if they are separated, it does not happen.
Excuse my bad English and I hope you have been able to understand everything.
