we moved the company’s website from local hosting to cloudflare, I created 3 cnames to point to the website, cname 1, website (pro traffic through customers’ paper cards) cname 2 qr (pro traffic via qrcode inside the store) and blog (for the blog)
They are all working except “QR”!
apparently the “qr” is only working on the PC, on any other device it points to the blog’s cname, even though it is not pointed to the same one, please test
blog.lazeraoponto.com.br
how do I solve this 
Sometimes it gives the error: err_name_not_resolved
Remembering that we use Cloudflare’s own DNS 1.1.1.1 in the company
