Although it might be related, that’s not the same problem.
And I can’t pick Byet over epizy.com for my domain as its a subdomain of rf.gd, which is owned by infinityfree and they set the name servers on it, not me.
No permanent solution has been suggested to me so far.
by the way, they consider the DNS issue to be solved as of May 5th.
I have checked this domain name, and it was only added to an account two days ago. Please keep in mind that within the first 72 hours, there is no reason to assume something is broken, because of DNS propagation.
Thank u everyone for the replies, as all of it helps in a way or two. The issue has been resolved, and it is due to the same reason as mentioned by Admin, my page was under 72 hours mark before, and that causes the issue. Now it is back online. Thank you again for the replies.
