I "might" have the same problem: do you have this message on your server ?
[Status]: Request for connection of testuser (ip: XXXXXXXXXX).
[Notice]: Authentication accepted (account: testuser, id: 2000002, ip: XXXXXXXXXX)
[Status]: Connection of the account 'testuser' accepted.
If you have it then your clientInfo is okay since you can connect to login server, but for some reason the client can't go further (char server).
That's the problem I'm facing right now
