longbeachmarina.net: No address associated with hostname
Do you have a public IP address? If so I don't know how to find it.
That's a must have. (To serve your domain name)

Sorry @Rip. Didn't see you responding for some reason.

NP... I knew you were lurking nearby!
At least we know where to start OP on his journey!

How can that even be possible? There is an A Record in GoDaddy for the site that resolves to my IP: 72.10.32.154

Please forgive my DNS ignorance on this.

Hi @joefino

@joefino

There is an A Record in GoDaddy for the site that resolves to my IP: 72.10.32.154

only your www version has an ip address - see https://check-your-website.server-daten.de/?q=longbeachmarina.net

Host	Type	IP-Address	is auth.	∑ Queries	∑ Timeout
longbeachmarina.net	A		yes	1	0
	AAAA		yes
www.longbeachmarina.net	A	72.10.32.154 Ashburn/Virginia/United States (US) - GoDaddy.com, LLC Hostname: ssd-ingeniumio.com	yes	1	0
	AAAA		yes

Your non-www doesn't have one.

So add the same A-record with your main domain (may be @ as domain name).

Thanks. I had no idea it was this messed up. I’m relying on the client’s IT team to make the DNS changes, and do not have direct access to it myself.

I wouldn't worry too much. It's a more common mistake than you might imagine (and a simple one to fix).
