CDN says host down yet it's up

Why can’t I edit my posts
I meant here, in these forums. I have no option to edit posts once I hit reply.

Everything is always https.

Do you have some caching in between?

No otherwise I would have checked that too.

Are you trying to ping your HTTPS Website or ping your IP address of the origin host/server instead
(not pinging the Cloudflare IP)?

I have two browsers up so can see when one works and the other does not. I am SSH’d into the server so can clearly see the services are up, the can see the logs.

I’m not following. Ping? I know when the CDN is caching or not. When it’s caching, I can see the CDN IP’s hitting the apache logging. When the CDN is off, I can see the hits direct.

What do you mean by switching to ‘standard’? What I’m explaining is that when we edit some pages on the site, this is when it seems to happen. Since there is no caching on the server side, it means that the CDN is for some reason not able to understand that we made a change or something and so decides to show an error.

The new pages/posts that we make definitely show up but as soon as I refresh the page from the browser that is going through the CDN, things break as explained above.

The error 521 or some other too?

Always the same, wrong host down notice from CDN. No other errors can exist since the site is in fact up and running and cloudflare is wrongly telling our visitors that we are down.
