The given host name could not be found. Check the following: 1) The host name was correctly specified. 2) The host is accessible.
Many systems include a "ping" utility that can be used to verify access to a named host. 3) The Domain Name Server (DNS),
or its equivalent, is available. If the DNS is not available, try specifying the host's IP number (for example, NNN.NNN.NNN.NNN)
instead of the host name. 4) The HOSTS file contains an entry that maps the host name to an IP number.
