Provider portal DNS resolution issue

What is the name of the domain?

What is the issue you’re encountering

No answer for the mentioned domain when using 1.1.1.1 DNS resolver, DNS query work fine when using Google DNS

What feature, service or problem is this related to?

DNS not responding/updating

Looks ok to me:
dig ethervision.gtt.net @1.1.1.1 +short
208.77.65.23
I assume just cache. What did you try to query it? gtt.net uses Cloudflare but ethervision subdomain doesn’t.

Hi,

Thank you for your follow-up on this topic.
I am using dig and nslookup to troubleshoot the DNS query resolution.

I have tried to separate workstations with different os to avoid any caching and so on.
gtt.net works fine, but the subdomain is not resolvable via Cloudflare for me, this seems to affect only Cloudflare DNS.
I am located in Czechia.
