Site goes down, getting 504 error in Cloudflare

[sulabhpuri]

Hi,
We have been facing a peculiar issue since the last 6-8 months. We asked on various other forums/wordpress and few people said it is to do with CloudFlare.

We get 504 error 10-15 mins randomly and then the site comes back up. What could be the issue?
We checked DNS maps too, that is fine.

Stunning thing is we found nothing in the error logs. Because of this we just moved server from Godaddy to Digital Ocean as well (VPS) and still the issue continues, hence people are saying it is a CloudFlare problem. Can anyone help?

If your server IP address ends in 132 then you currently have a security issue.

Why you should choose Full Strict, and only Full Strict

Unencrypted & unverified connections Imagine you open Paypal and suddenly get that warning [image] Would you continue? Probably not. For decades leaders in IT security have advocated that people upgrade their sites from unencrypted HTTP to secure HTTPS. And for a reason, everything you send via an HTTP connection is sent in plain text and can be intercepted at any point between you and the server. Equally, you’d probably not proceed if you got such a warning, right? [image] That’s when th…

The server IP does not end with 132.

If your server IP address ends in 132

And it actually conflicts with this statement.

@sulabhpuri

we just moved server from Godaddy

132 is GoDaddy’s IP address.

Yes, so we are no longer on Godaddy but Digital Ocean, and are still getting this error. One thing is constant which is CloudFlare on both servers. Hence asking here as others pointed it out, it could be Cloudflare issue

Error Try the suggestions in this Community Tip to help you fix Error 502 / Error 504: Bad Gateway / Gateway Timeout. Background The 502 / 504 errors are quite similar. Generally, a HTTP 502 / 504 errors occurs because your origin server (e.g. your web host) is returning this code to us, and Cloudflare returns this code in turn to your visitors. They are caused by a problem connecting to an upstream server - meaning your server is trying to initiate a process and this fails to work as expecte…

132 is GoDaddy’s IP address.

That is causing a conflict (explains the 504 error)

To fix: Allow ALL IP’s in this range

IP Ranges

This should help resolve the conflict @sulabhpuri

I don’t get a 504 error at all

And it actually conflicts with this statement.

How can a conditional sentence conflict?

[sulabhpuri]

yes, it randomly comes 10-15 mins the site goes down and comes back up.

[sulabhpuri]

We thought of that, so switched servers from Godaddy shared to Digital Ocean VPS, still the problem is there. But cloudflare is on both of them, so people pointed out it would be clouflare.

[AppleSlayer]

So the error is sporadic?

[sulabhpuri]

yes. So need a solution, if anyone can help.
