Hi, from this last days we are suffering a weird behaviour in our website www.classonlive.com.
Suddenly if we browse to our home, sometimes some resources which should be served through cloudflare remains in pending status so the website doesn’t load os load very slow until we refresh again . This behavior increases if we clean browser cache. During first visit is slow, then normal, then slow again or even doesn’t load.
If we change from proxy to only DNS, the website loads fast always.
I don’t understand what is happening. I have returned to proxy config, and i have turn off cache and purge all files but the problem persists. I dont know if maybe the WAF which I have in my plan is the responsible for this o any other functionality.
I need my website goes thorugh proxy in order to use the WAF configurantion, Cache, etc
so, have anyone suffered this problem during the last 3-4 days and has a solution?
I have the Cache configured as Standard
I test with Rocket but I saw some warnings in browser console similar to "The resource https://www.classonlive.com/js_common/external/global/restricted.js was preloaded using link preload but not used within a few seconds from the window's load event. Please make sure it has an appropriate as value and it is preloaded intentionally." and the resources were not loaded so i switch off Rocket.
We have some Firewall Rules but regarding to forbid traffic from specific countries. Nothing special. But the Waf has several options enable and also Managed Rules (It always was with these options enabled)
I don’t use Cloudfront with custom domain, so Cloudflare and Cloudfront serve both different resources.
It is not possible the Cloudflare Firewall blocks Cloudfront requests.
When I see the Chrome console, pending resources to be downloaded are always those which have to be served by cloudflare not by cloudfront. and as aI said before is something regarding the proxy, because if i change to only DNS and resources are served directly from origin and cloudfront everything is working.
