FTP not connecting

FTP is not connecting to my site for some reason. It was a few minutes again and now I can’t connect again. The password and host and username are all recognized by ftp, but it will not connect at all. Help?

I again discovered the problem and fixed it myself… I checked the German side of this site and from the German that I know, I discovered that the problem is on server three and all you need to do is add a www. to the beginning of your host url on your ftp program. It connected right away.

the adding of an www. in front of the server adress is one way, to solve the dns problem for a short time, after three hours you could delete the www. infront of the server adress, because after this time your pc gets new dns data from server
alternative you can try to delete dns cache
start->run->ipconfig /flushdns
