There are 3 common reasons your FTP program may time-out when trying to connect to upload files.
1) Your firewall may be blocking your access. Try to turn on PASSIVE TRANSFER mode, which is an option in all FTP programs. In Ws_FTP, it is under Session Properties > Advanced Tab > Passive Transfers.
2) You may have the wrong Host Name. If your domain is pointed at our servers, then use yourdomain.com as the host name. If it's not pointed there yet, try to use web.hosting-advantage.com, or use your IP address, which you can find in your Control Panel under WEB OPTIONS.
3) Your disk space may be filled. To check, log in to your Control Panel. On the main page it will show disk usage. If it is over the limit, you will need to either delete files, change your plan to the next level, or increase your disk storage by clicking CHANGE under Disk Usage.
