When you can't connect to the FTP server using FileZilla and you encounter some connection errors like the screenshot below, it could be that your FTP login details are incorrect:
In this situation please check that you have entered your FTP login credentials correctly. The information should be as follows:
- Hostname: your domain (eg domain.com)
- Port: 21
- Username: account username
- Password: account password
If you still can't connect to your FTP account, we suggest resetting your password from Plesk.
