I recently switched hosts for my site and matched DNS records, the problem is that my host will show that the nameservers aren’t directed towards them. And constantly give error 521 when trying to visit the website. I changed the host again, matched the DNS records, and am getting 521 again. I contacted the host about the issue but they say that their servers are working perfectly and its a problem with Cloudflare. This is my second host so I’m pretty sure that this problem can’t be with the hosts. Would really appreciate if someone could help me figure this out.
