Error message in Dreamweaver - Remote host cannot be found

I recently started a new site and as of wednesday the connection was working.  But when trying to log in today and yesterday I received this:


An FTP error occurred - cannot make connection to host.  The remote host cannot be found. 


Any ideas of fixes for this?  I've tried many things already and hope it is something simple that I'm not noticing.

Only thing I can think of at the moment is to check your ftp settings. specially your server settings. Sometimes it happens with Dreamweaver. It's fantastic when going right......
