The resolution was to make sure the network was set to a static IP:

# The primary network interface
allow-hotplug enp4s0
iface enp4s0 inet static
address 192.168.0.16
        netmask 255.255.255.0
        gateway 192.168.0.1
        # dns-* options are implemented by the resolvconf package, if installed
        dns-nameservers 1.1.1.1 1.0.0.1
        dns-search geekdecoder.com

The second issue was to make sure there was a host entry. Comment out the 127.0.0.1 and make sure to use the full host.domain host as below. Leaving out the end “px1” caused the issue.

#127.0.1.1      px1.geekdecoder.com     px1
192.168.0.16    px1.geekdecoder.com     px1
