Unable to connect via SFTP with windows client

[davidrot]

Hello,
I am unable to connect to my vps via ssh key (ed or rsa). It is working for me with the same credentials on mac (7.4.1). I have tried several versions for windows 8.2.0, 8.0.0 and 7.10.0. I have tried two different remote machines.

I have checked the auth.log, first 4 lines are from windows, last line is from mac.
