Seriously. I get the static content updated on the server side and it refuses to update until like half an hour later. I honestly do not know what goes wrong here. Everytime.
I tried both of those page rules.
but neither seemed to work.
Every once in a while, I purged cache manually on Cloudflare caching section and things got instantly updated. Most of the time, they did not. And in those embarrassing cases it usually took half an hour for content to go refreshed.
There certainly could be but that fully depends on your host’s setup. It could be also your browser cache or a local proxy. You should clarify this with your host or (if applicable) your local network administrator.
