I register a domain at Namespace and I set it up under Cloudflare for security purposes, I'm trying to use the domain on my vercel project which vercel requires that I configure the Cloudflare nameservers to intended vercel nameserver or alternatively use A record. First, i can not change the name servers on Cloudflare and i have already created A record on cloudflare added the giving address from vercel to the A record on Cloudflare, still, my vercel won't work, reporting invalid configuration.. Please walk me through how to fix this.    See the screenshot below  https://prnt.sc/vr9boi  https://prnt.sc/vr9aa5
