Hi, when I open my subdomain “database.emfasandbox.com”, cloudflare shows me error 521: web server is down. The subdomain is an A record that points to my public ip, server I host myself. But the problem is that when I point another cloudflare domain “falta.pro” to the exact same public ip (my server), everything works perfectly fine, even with ssl. I have tried removing the “emfasandbox.com” domain from cloudflare several times, deleting dns records and nameservers, the problem is still the same. I also wondered what are the chances that my ISP could be blocking the domain? Thx
