Nope.

Directory has permission 0700, file has permission 0600, just to be sure 
I've execute chmod on both.
I can access they key but I still experienced the issue

If I manually execute lftp


~~~~
$ lftp sftp://cygwin:@cygwin.com
lftp cygwin AT cygwin DOT com:~> cd .
cd `.' [Connecting...]

and hangs.

I'm not sure how to debug the issue further, and the relation between 
all tools.

~~~~
$ sftp sftp://cygwin:@cygwin.com
cygwin:@cygwin.com: Permission denied (publickey).

I guess lftp/sftp does not support the variable SSH_KEY, as I get the 
same "Permission denied (publickey)." error with "ssh -v 
sftp://cygwin:@cygwin.com", and I see that there is no attempt to use my 
ssh key

Also following command does not report an error:

~~~~
sftp -i $SSH_KEY sftp://cygwin:@cygwin.com
