Resolver issue

I cannot resolve a certain URL(https://atomtech.in) when using Cloudflare DNS(1.1.1.1), particularly from my location. It is accessible using Cloudflare DNS from other locations.

[[email protected] ~]$ dig @1.1.1.1 atomtech.in

Here is the result from DNSViz: https://dnsviz.net/d/atomtech.in/dnssec/

I have also opened a support ticket. The id is: 2069070.

Hi @xtra, do you still see the issue? I check there was no SERVFAIL in the past hours. The EDE in your log showed it was a connectivity issue.

Hi xtra,

This issue is most likely with your local DNS resolver since you have mentioned it works from other locations but not from your location.

I see the ticket #2069070 has been resolved so I will go ahead and resolve this issue.

Thanks,

Rui
