The only way to access the box is from the IP address.
https://box.r3df0x.net is where the box should be available. The nameserver is the box so it configures everything.
I can only access it from https://188.8.131.52 and I don’t know what is causing it.
Looks like it’s failing DNS lookup.
Thank you. I just fixed it. I was writing a Digital Ocean support ticket after I wrote one to Gandi asking if anything could be causing a problem and I remembered I added a firewall using Digital Ocean’s new feature. I added DNS ports to the firewall and it works now.
