There were other two-post with similar issues, sendgrid require to add their 5 cname http://prntscr.com/1rmlqtg to verify the domain but Cloudflare is not propagating the update. Even using external tools to check the cname like dnschecker.org http://prntscr.com/1rmm0gy
Those image links send me through a CAPTCHA process. If you can’t directly attach the images to the post, what’s one of the hostnames of yours that’s using a CNAME? Or a link to the DNSChecker results.
Besides the 5 cname from sendgrid the only other cname that i have is www that redirect to the main domain
That looks right. It’s possible this domain is controlled by a different account at Cloudflare. If you check whois.com, it should show you the two .ns.cloudflare.com name servers that match the ones at the bottom of your DNS screen at dash.cloudflare.com
The nameservers are correct
