Could not Deploy <Project> to <host>

This error has the following cause and solution:

• VSS was unable to open a connection to the specified ftp host and deploy your project.

  Check your network connections, and check that you've entered the correct syntax for your ftp host. This error can also occur if your ftp host is not available at this time.

  This message can also mean that you are out of disk space. It can also mean that you don't have permission to write to the location although you may have read permission.
