FTP will not connect: No such host is known.

I've been dealing with web hosts for the last 18 years. Not once have I ever dealt with a problem like this with FTP. Each time I try to connect, it says "no such host is known."

 

My settings:

 

Server: ftp.mysite.com

User name: name@mysite.com

Protocol: FTP

Port: 21

 

It's like this on all FTP clients. I've read that GoDaddy is pretty horrible when it comes to FTP. I hope not, but so far it seems to be the deal. Has anyone dealt with this same issue? If so, how did you fix it?
