I gave it a try. It should also have exceptions for relays running on localhost, 127.0.0.1. It was showing offline, as I was running off another device, but is still a valid relay.

That would make sense. Either disregard or a 3rd n/a return for local subnets. I don't know what's up with my 5. They're all connected to other services that are returning as online. Odd.
