[PROBLEM] Connection 2010 SF

[chouya]

Hello,
I use the modified client 2010 and the new 2010 file server.
In trying to connect, the client gets stuck on "You'll be connected to the server".

AUTH: SYSERR
SYSERR: January 12 10:59:08:: Process: UNKNOWN HEADER: 23, LAST HEADER: 255 (13), REMAIN BYTES: 59 fd: 16

Do you have an idea? thank you in advance
