So, sshd is sucessfully establishing the connection but the internal
sftp server is stopping without producing any output.

Adding some debug flags to your sshd_config Subsystem declaration might
elicit a little more information, e.g.

Subsystem      sftp    internal-sftp -l debug3

You could also try "ssh -p 2222 user@host" and seeing it produces any
unexpected output.

-d
