Is the ISP blocking the domain, or is its DNS server returning nxdomain for it? I've seen ISPs provide modems which use the ISP's DNS as a default (via DHCP) unless configured otherwise. Try running `dig mydomain.com @1.1.1.1` to check if that returns the right IP.

Not sure what you can do if they're just serving whatever they want from their own DNS other than telling users how to specify another one. Maybe dnssec is relevant?

Unfortunately I am here only with a phone. Although I have tried it on multiple friends phones whom live here on mobile and broadband wifi connection, same result. Also installed a trace route app and it just defaults to 0.0.0.0

My domain and same sever IP have been up for over 5 years
