No luck, unfortunately. I tried many times with new users, changing pass etc. The username and pass matches.
A crude workaround is go to the settings in the “Encryption” section and set “Use simple FTP” .
Where would I find this?.
FInally if all fails contact service provider to check whether they block port 20 or something else see this FTP issues on DigitalOcean - #20 by ljchuello
I can telnet my server on port 21, and it responds fine as OPEN. Also, I would have thought then I would get a different error. I am provisioning a VM on GCP and installing it on there to see if the issue persists. Will allow port 21 via the firewall.
