[quote=176381:@Rick Araujo]Mark, download Cyberduck and try to connect to SFTP on port 22. Let’s see what it returns.

I use Ipswitch as my usual ftp client. I was able to set up and successfully establish an SSH/sFTP connection on port 22 with that to my server.
FYI - I did have to go to my server and enable SSH access - which I did before the latest issue above, where I connected but now am getting an error code 23. I am now see if Christian can identify anything obvious from my use of CURLSMBS that would cause that error.
