This site can't be reached but using a VPN to different server it works

Hi,
Today I am not able to access my site ( https://www.aiwo.com/ ) and it’s showing me error:
This site can’t be reached
When I use a vpn to different server, it works normally and am able to access it. I can’t figure out the problem.

Please help me.

Are you by any chance located in Iran?

Whats the output of these commands?

ping aiwo.com
ping www.aiwo.com
nslookup aiwo.com
nslookup www.aiwo.com

I’m located in india.
Here is the outputs of the given commands:

Hmm, interesting. DNS lookups fail altogether, but a ping works, though with two different IP addresses and only the naked domain returns the Cloudflare address.

Well, your host file does not seem to contain your domain then, right?

So it would be an issue with your DNS resolver. Your naked domain resolves fine but the “www” host does not. Though it is strange that nslookup timed out.

For now you should probably wait and maybe it is just a propagation issue. Otherwise you’d need to contact whomever maintains your nameserver or switch nameservers altogether.

Just to double check, can you run these commands again?

nslookup aiwo.com
nslookup www.aiwo.com
nslookup aiwo.com 1.1.1.1
nslookup www.aiwo.com 1.1.1.1
nslookup aiwo.com 8.8.8.8
nslookup www.aiwo.com 8.8.8.8

Here is the results:

C:\Users\siam10>nslookup aiwo.com

There is something off with your resolver. Again, it is weird that it resolves for ping but not nslookup.

what should i do about the issue? is there any steps can i take?

As I wrote before

Thank you sandro for your valuable time and quick reply. I’m really satisfied :smiley:. Once again thanks.
