on my website, on some URLs, it randomly appears to redirect to 404 that is not on my server.
URL is One moment, please... you will see that it’s redirected to https://wpspeeddoctor.com/z0f76a1d14fd21a8fb5fd0d03e0fdc3d3cedae52f?wsidchk=5207581
Another website has the same issue on this URL: One moment, please...
When I manually purge the cache, the redirect disappears and it all works fine.
I have set the page to cache everything and I’m using firewall too, but not fight bot mode.
I’ve found this answer Cloudflare caching issue? - #6 by cbrandt but it doesn’t make any sense to me and I think it’s a different case.
So why does it occur and how to prevent it?
