- Your firewall could be blocking it.
- Make sure you have the IP address in your welcome email for host name (only the numbers; don't add ftp, www or anything else).
- Make sure your username and password are the same as your control panel username and password.
- Some FTP programs require a path in order to connect. Your path would be /home/YOURUSERNAME/public_
If you are behind a router, please enable passive FTP mode.
My FTP is really slow or disconnects often. Why?
Go into your FTP options and see if passive mode is checked ,if it is, uncheck it. If it is not checked, try checking it. This should solve your problem, assuming the issue is not with your actual connection to the Internet.
