SFTP login failed (private/public key test)

, ,
1

We are unable to get a local SFTP test working with public/private keys - the local SFTP server (Port) is running and works with a username and password, however when we add the private/public key it fails. (Please see attached).

How can we fix? Is it the format of the User Public Key path?

Thanks.

The Server Port also has these set:

Require Password Authentication [ON]

Require Public Key Authentication [ON]

We got this working by just using public-key authentication (which is want we wanted):

  • Port: Only selected public key auth
  • User: ensure the password AND public key auth is unchecked.

It seems the “two-factor authentication” checkbox may be needed in the folder management if you’re using both.

In addition to this, we received a “No supported authentication methods available” error, so we needed to use the one-line version of the public key - so rather than:

---- BEGIN SSH2 PUBLIC KEY ----
Comment: “rsa-key-20121022”
AAAAB3…
---- END SSH2 PUBLIC KEY ----

… we had to use:

ssh-rsa AAAAB3N…
