WinSCP: the server refused our key
Ok, I have a working server connection on our production machine. I need to reproduce this on my development machine so that I can transfer my own files. Everything is the same, right down to the OS.
When I try to connect, all I get is:
The server refused our key.
Here is my log file ...

You do not have the correct private key validation setup.
Make sure to add the public key to ~/.ssh/authorized_keys
on the server.
You will get a public key fingerprint in the correct format in PuTTYgen in the public key to be inserted into the authorized_keys file when you upload your private key.
For more information, see Configuring SSH Public Key Authentication .
