Website unreachable after pointing DNS to cloudflare

Hi everyone, please can you help me configure the DNS, I don’t know if I was right in disabling the proxies in this way but the wen site doesn’t work.
I’ll give you some premises:

I set up flexible HTTPS in cloudflare.
On my origin server I enable Redirect HTTPS
I deleted the www record

The site doesn’t work anyway.

Thanks everyone for the help
