I’ve registered a new domain on Cloudflare which I’ve connected to a remix app hosted on render.com. But no files are beeing caches in the Cloudflare CDN and I can’t figure out why. Any tips on how to debug it? I’ve been struggeling a long time with this, reading docs and trying differnet settings, so any help would be usefull 
The domain I’ve registered is tekkendocs.com. The javascript files have set Cache-Control: public, max-age=31536000, immutable, but the header Cf-Cache-Status gets the value DYNAMIC.
I also tried to add a rule to cache everything. Have set this to:
tekkendocs.com/*
Cache Level: Cache Everything
I’m currently on the Free plan.
I saw from another thread that I could be helpfull to run a curl command. The result is as following :
$ curl "https://tekkendocs.com/build/_assets/global-2OGRYG6G.css" -svo /dev/null --ipv4 --connect-to ::x.x.x.x
