Cloudflare Proxy with WS

you probably can, not sure why, though, ws is fully hosted on cloudflare

To have geo blocking etc.

should work, we haven't tried to put cloudflare in front of cloudflare though

works fine with the features I've tried

there are plenty of whys... zaraz, workers, custom rules, etc

Same for me here.

Cloudflare proxy works with no issues ❤️ gives you all the fun toys.
