Getting this error [504] Gateway Timeout

My website URL is: uzain.com

I bought this domain a week ago. I have setup NameServers as ns1, ns2.epizy.com. Its been more than 3 days ago. Everytime i open this domain i get this error “[504] Gateway Timeout” Please help.

It seems like the IP your website is in is currently down due to an attack. You need to wait until the IP is restored back to normal, or you can remove the domain from the old account and add it on a new account with a different ID.
