Hello, i have a problem.
error 522 on my website: https://grandfatherclock.ru/
I contacted the hosting provider Reg. ru, they reported that there was an error on the side of CloudFlare, to check they advised to change the DNS nameserver “maria.ns.cloudflare. com; matt.ns.cloudflare. com” to the default value "ns1.reg. ru; ns2.reg. ru "that I did and the site started working. Then I returned the nameserver to the Cloudflare settings - it doesn’t work again. Help, what needs to be done?
