If a port-level network connection is made to the remote host, but the host is not listening
on one or more of the selected ports, the "Port connectivity test failed" message appears in
a yellow banner. The nmap command output is listed below the banner.
Any remote port the host is not listening to has a state of "closed." For example, you might
see this yellow banner when the node you are trying to connect to is in a pre-installed state
and the StorageGRID NMS service is not yet running on that node.

If a port-level network connection cannot be made for one or more selected ports, the "Port
connectivity test failed" message appears in a red banner. The nmap command output is
listed below the banner.
The red banner indicates that a TCP connection attempt to a port on the remote host was
made, but nothing was returned to the sender. When no response is returned, the port has a
state of "filtered" and is likely blocked by a firewall.
Note: Ports with "closed" are also listed.
