are you forwarding request to cloudflare through unbound? or are you using unbound recursively? What does your unbound config look like then? I am using unbound recursively without forwarding to any servers.

try disabling the IP ratelimit option using a comment #, unbound might be overzealous

e.g. #ip-ratelimit: 0

You could try making sure all those cloudflare domains are whitelisted for you in slynet, and your blockers. Aside from that, there would be not much else you can do aside from tell unbound to forward those specific request to a dns server.

Issue seems to be with my ISP? Is that possible? When using unbound, does ISP come into play? The reason I'm saying this is because I'm not able to access the site using mobile broadband too. Both home internet & mobile broadband are with same company.

Could be a number of things. Your isp could block them , or they could be blocking your isp.

My suggestion in this case is to create a forwarding rule in unbound that forwards request specific for that domain to like 8.8.8.8 for example. You can even leverage unbound DoT to ensure the requests are done over encryption.

How to do that? When I check my DNS server online like on tenta.com/test my WAN IP comes as DNS server, correct? So does my ISP part in DNS queries. Looks like my ISP has blocked .gq but I thought when I use unbound I bypass ISP restrictions?

Works if I do this. How to add multiple domains? Also, why does it work this way? If my ISP is blocking it, I thought unbound bypasses ISP for DNS?
