Re: FTP connected but unable to transfer files
Hopefully this helps some of you. I had same issue.
Using filezilla. SFTP to manage WP account.
Instead of using the domain name as the host I used the IP. Was able to upload fine. I tried cyberduck, disabling my firewall, punching a wall, but none of it worked.
Either it was a coincidence or just using the IP address solved the issue.
