Error 521 Web server is down


#1

Hi, everyone!
Today 2018-09-27 I’ve got 521 error on domain kuda29.ru. Web server was running. There are several sites correctly working on the server, but only this domain is under CF and returning 521 error.

Domain started normal work only when I switched Status on DNS page to “DNS only”.

I’ve got an answer from my hosting company:

From the server side there is no restrictions to any of CF ips. From what ip CF has made requests to kuda29.ru and what response was from the server?

And you didnt make any other change?

I wonder if that issue could be related to Nameserves not working
@cscharff @cloonan

Maybe try opening a support ticket (email to support[at])

Got answer from the CF support. They still recommend to ensure that my hosting provider is not blocking CF requests.
I’ve already ask my provider about this and inform CF support about provider’s answer. But now I’m forced to ask them in more hard way )
