Question ssh connection closed immediately after logged in

I'm using Ubuntu 11.04. I've bought an account in a SSH sever.

loveright 02:41:54 ~$ ssh gqqnb@
gqqnb@'s password:
Last login: Sat Jul  2 14:41:53 2011 from
Connection to closed.
I've tried many times, the issue persists. ssh localhost is ok.

I go to Windows, run Bitvise Tunnelier. After providing corresponding information, connection is established.

14:48:07.381 Starting a new SSH2 session.
14:48:07.383 Connecting to SSH2 server

So, how can I fix? Any hints?

It's fixed now.
I contracted the custom service, he said it was because of the configuration of the server. He fixed it and I can log in successfully.
