Error (502) Currently Offline

Hello CloudFlare Community,

I have recently discover an issue error over a website of my own “Discord Server” on the browser. It is being supported by “” as a “Discord Bot”, once I select my premium server by purchasing it, it gave me an “Error 502” (Bad Gateway). I was customizing my server for 2 hours. Next day I got back on to customize my server and…
It say’s:
Cloudflare Ray ID: 520dfa73ced4c7d9 is currently offline. However, because the site uses Cloudflare’s Always Online™ technology you can continue to surf a snapshot of the site. We will keep checking in the background and, as soon as the site comes back, you will automatically be served the live version.

It has been a couple hours, they said that it will be back on in (minutes). They said that my “Browser” is
(working), “Denver” from “CloudFlare” is (working), last “” as “Host” is (Error)

Please Help.
