I'm getting Your Hostname is: srv2.xryu.org and it resolves to IP: (ERROR: You don't have a valid hostname set!)
I have programmed the "DNS" Server and Cloudserver to use my other IPv4 37.49.224.243 and I had my VPS Host change it manually since it wouldn't change.
Everything in my "DNS Records" point to the new IP 37.49.224.243 of srv2.xryu.org
/etc/hosts (127.0.0.1) srv2.xryu.org & 37.49.224.243
srv2@xryu.org/etc/hostname srv2.xryu.org
Zone: srv2.xryu.org.db Points to 37.49.224.243
/etc/resolv.conf - srv2.xryu.org 37.49.224.243
Everything points to the correct IP; YET I'm getting INVAILD Hostname. I don't get it. the rDNS Checks out. I also added srv2 on Cloudflare to point to 37.49.224.243 and mail to 37.49.224.243 yet it's not registering! I even restarted the Bind DNS Server several times after I rechecked the DNS Zones.
