CloudFlare issues on xenforo.com

[Sadik B]

Hello guys, this is the 4th time I have seen this screen in last few days.

 

[Paul B]

I also get it occasionally.

It's related to CF.

 

[m1ne]

Not happened once for me.

 

[Alpha1]

When it happens it keeps happening. Firefox can crash on it.

 

[Amaury]

No issues here.

I stopped using cloudflare because of this.

Hey @Brogan
This usually happens on Flexible or Full SSL configurations on Cloudflare. If you switch to Full Strict , this shouldn't happen any further.

 

[Paul B]

Thanks @Mert, I'll let Mike know.

And happening again

In the last week or so, my experience of xenforo.com has become extremely poor and my usage very troublesome.

This ...


And this ....

.... appearing regularly.

Hover over alerts, and instead of the list of alerts appearing, the cloudflare 'error' appears in the alerts model window.

Type in a post/reply (like this) and auto-save will automatically redirect me to a cloudflare error page

Load threads/resources, and after a 10 sec, or so, timeout period of waiting, I'll get the cloudflare error or cached version page.

It's approximately 15% of my browsing time and page loads on xenforo.com at the moment, affected by these cloudflare issues.

If xenforo.com cannot get cloudflare working properly, then its clearly not the right CDN (as is my experience with cloudflare) for an XF site. Or is xenforo.com server having real issues and cloudflare reporting these issue indeed correct?

P.S. See my sig for a CDN that will not give these errors all the time

I also seen that at least 5 times during the last week. (Australia)

XenForo can work fine behind Cloudflare, the webserver might require a bit of tuning so the true IP is restored before any rate limiting is applied.

Thank goodness they now show an error message. Previously, when this error occurred, all you got was a blank page.

It's worth noting the CloudFlare specifically listed issues with Sydney and Melbourne (with a fix rolled out today).

We are monitoring this.

with a fix rolled out today

If this is the issue, hasn't worked.
Just now .....

522 https://support.cloudflare.com/hc/en-us/articles/200171906-Error-522-Connection-timed-out

 

[Paul B]

FWIW, I haven't had any issues for weeks now.

 

[Amaury]

I'm curious as to why it only affects some. I've never had issues at all and still don't.

This is an issue with their SSL termination servers in certain datacenters, as Mike alluded to. I experienced the same issue with their HK servers, meanwhile US servers worked fine. It has zero effect on non-SSL traffic, by the way.

BTW @Mouth the 522 you referenced and the 525 mentioned by the OP are different issues.

 

[Paul B]

They are different issues but I merged two separate threads as they both relate to CF and it's better to keep all of the feedback in one thread.
