Always Online never works (502 error)


#1

I often see the Cloudflare AO crawler in the logs, reading a couple dozen pages at a time (starting from the homepage, obviously).
Well, whenever I come across a 502 error, the Cloudflare error page says that they can’t communicate with the other server due to a 502 error, but AO is not available because no page has been cached (not even the homepage).
Bottom line: Always Online never works for me.

This may help you out.

Hi @komarEX I had already read the help page before I wrote my post. Anyway, the page confirms that “In order to trigger Always Online, your web server will need to be returning a standard HTTP Error code of 502 or 504 timeout” which is what happens in my case (502 error, as the Cloudflare error page says), without triggering Always Online though :confused:
Reading the comments here https://blog.cloudflare.com/always-online-v2/ it seems I’m not the only one.
