I can't get this to add to my cluster for some reason?

Host names may not contain underscore characters.

See https://en.wikipedia.org/wiki/Hostname

Thank you, I noticed that was the problem after wiping both machines and restarting over. I got it fixed now, and I couldn't find that link for some reasons earlier, appreciate your time!

Hello, It is perfectly valid to have underscores in the hostname as it is said in RFC 2181, section 11, "Name syntax"

Examples of servers with '_' in their names:

_jabber._tcp.gmail.com
_sip._udp.apnic.net.

Route 53 and other DNS servers accepts hostnames with '_' characters.

The UI does not accept names with '_' though. Could you please fix it?

PS: The restriction is with domain names. But hostnames inside the domain name with '_' are legal and valid names.
