I got exactly the same problem. Everything seems to work (it works using the same parameters in sshfs-win-manager). But then the connection is closed and the drive is not mounted.

You can see an error in the output log towards the end:

debug3: read - ERROR from cb :87, io:0000028E7809A6F0

Did you manage to solve it @Lotharyx ?
