I hope this question has never been asked before. Our website is being blocked by certain routers or ISPs (we can't tell). We are hosted in Singapore (AWS) and we use Cloudflare to host our DNS. Our website is http://www.nibble.id.
On our office internet/router it works fine. On all our team members personal home internet it works fine. However, on some shared internet (free public wifi, restaurant wifi, office wifi), our website is blocked. The DNS can't be looked up.
We recently tried to sign up for an AdSense account and even Google can't look up our website.
Our developers are certain everything is OK and we're really scratching our heads on this one. We would really appreciate any sort of insight on what might be going on. Thank you in advance!
