May I ask if chip.ns.cloudflare.com and diana.ns.cloudflare.com were set and added to the domain name registrar before you’ve added your domains to your Cloudflare account?
Should they be: rohin.ns.cloudflare.com and sima.ns.cloudflare.com instead?
Did you checked if the assigned nameservers for your domain(s) under your Cloudflare account are correct ones?
