No Permission - Error 3

So after hours of trying to debug I still can't figure out why I can't modify any type of file within WinSCP. It has worked for all other hosting services that I have used.

I have tried:
Opening port 22
Installing OpenSSH
Changing permissions on the server
Changing owners
Modifying the OpenSSH config
I am signed in through the administrator account on the server with WinSCP on my home computer.
