[Solved] Request To Whitelist Cloudflare Ips

[Jeremy93]

Hi would it be possible for Helio to completely whitelist all cloudflare IPs?

 

I'm having some problem accessing one of my sites through one of cloudflare server i'm guessing the IP got auto blocked by stevie because of too many request made by the location server (definitely not just from my site as i don't get alot of visitors) for other users sites also.

None of those IPs are blocked.

It's working now, also I got a reply from Cloudflare:

 

 

Hi,

This looks like a case of your web host/web server blocking one of our IP's, I had a look at our logs and can see all the 522 errors from this time were returned from one specific server:

216.218.192.170 nc: connect to originip port 80 (tcp) timed out: Operation now in progress

I ran this test twice to ensure this wasn't a one off and the same IP timed out both times, I also observed high amounts of packet loss which is expected as one of our IP's is being blocked at your origin server:

In order to fix this issue you will need to ensure your server/web host whitelists all of our IP's, our IP's can be located here.

I hope this information helps fix the issue but if you are still having issues after whitelisting our ip's please let us know.

Do you think at that moment it was a temporarily IP block or routing problem?
but it was quite strange as only 1 css style sheet could not load while the rest loaded just fine.
