Hello @joefino ! 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:

Please forgive my DNS ignorance on this.


Hi @joefino

only your www version has an ip address - see

Host Type IP-Address is auth. ∑ Queries ∑ Timeout A yes 1 0
AAAA yes A Ashburn/Virginia/United States (US) -, LLC Hostname: 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).
