Unable To Resolve Host ... Temporary Failure In Name Resolution

coffeeman

I've been trying for like 2 days to get my domain to resolve to ip address I've never such using using different system this this which leads me to think there is issue with this system.

What I've done so far

verified my resolvers are pointing to google.
checked firewall
Active Internet connections (only servers)

at this point and time I'm about to toss in the towel give up on word ops I was assuming this would be simple boy was I wrong. I may try different os then Ubuntu but I have doubts

It's normally super easy - just a case of adding a site (wo site create...) and point the DNS to the server IP.
Is UFW enabled? And open for http/https?
Do these return correct IP address:

dig yourdomain.com +short
nslookup yourdomain.com

Non-authoritative answer:
Name: maskdomain.com
Address: 15.204.xxx.xxx

** the maskdomain isn't the actual domain ** but so far everything checks out but that server ip adress makes me wonder

I removed a couple of other real domain references that were still in your post (assuming mr*****ris.com is the real domain). Not sure if you made any further changes but that site loads fine for me and shows a fresh WordPress install.

(For nslookup it's the address line that matters so if that IP is correct it's fine)

coffeeman

Yes thats correct. I've cleard my cache for some odd reason I'm not able to get to that site. I tested on my mobile data it works tried vpn didn't seem to work. I'll try it on different vps perhaps its the vps ip address.

coffeeman

I figured out what I was doing wrong and got it working. thanks for all your prompt response. I feel so silly.
The solution to help others 1. make sure your domain resolves then make sure your hostname is updated on the vps.
