Just trying to make sure I'm doing everything right on my end -- can't connect to a SFTP site, admin insists I should be able to. However, I often connect to other servers with no issues...

I keep getting No supported authentication methods available

From my log:

Do I just need to be provided with a Public Key? Does a server setting need to changed?

Thanks for the advice.

Ask the server administrator for authentication method allowed on the server. Public key might be a solution.
