Option 2 in MX is still reporting an Invalid SshftpAuthentication specified. - I don't know whether that's from MX or a failure response from the Host.We only support FTPES (FTP with explicit SSL/TLS encryption)
connections. For these the client connects using the standard FTP ports,
then issues a comment to switch to a secure connection before
authentication takes place. This is different from FTPS, where the
client initially connects to a secure port, which we don't support.
Since your software doesn't support FTPES, I have enabled SSH on your
account, which will enable SFTP protocol. Please try again using option
2 (SFTP).
This is a problem I didn't have under Cumulus - using SFTP .
