Configure SSH Connector Error

I have some difficulty uploading a private key when configuring a SSH Connector. The error I receive is “Can’t upload private key: Key “OPENSSH” is not supported.”

I am able to use this private key directly in cmd after installing openssh.

Is there a particular format I should be using rather?

The OpenSSH format should work.

Try generating a key in PuttyGen then convert it to SSH as described here: SFTP doesn’t recognise private key
