Then it might be a problem with your server? Did you already contact the server administrator for assistance?

not yet. still trying to get in touch with him. just didnt know if anything else could be a problem before that

The server seems to be online. Try to add SmartFTP to the exceptions in your software firewall and antivirus product and then try again.
