Why do I get a “Connection to [host] closed by remote host” error over SFTP connection?

I'd like to connect as user to a remote host through SFTP.
Moreover, I'd like to land into a specific directory (say /home/user/dir). I've created user with default working directory as /home/user/dirand set a /home/user/.ssh/authorized_key file to host my public key.
However, upon connexion using sftp -P 7000 user@host.com and after typing user's password, I get the following error immediatly: Connection to host.com closed by remote host. Connection closed.
Any idea about where it might come from (or how to debug that kind of issue)?
UPDATE
I was finally to connect as user because authorized_key didn't have the proper rights. However, I got the exact same error message while trying to land in /home/user/dir with another user (say user2) which was granted group access to /home/user/dir. But as it turn out in this response, SFTP chroot jail does not allow that by design. I'll try to use symbolic links between /home/user/dir and /home/user2/dir to solve this issue.

Did you set /home/user/dir as your user's $HOME ? or what else did you do to "land into a specific directory" ? Did logging in work before you changed that directory?

How to debug
First step is running command with verbose flag:
sftp -P 7000 -vvv user@host.com
Analyze of log
Connection are estabilished
debug1: Authentication succeeded (publickey).
but, ssh cannot set non-blocking mode:
debug3: fd 1 is not O_NONBLOCK
Connection to host.com closed by remote host.
Probably Your shell initialization file (.bashrc, .bash_profile, etc.) breaking ssh connection
