Do not hardcode IP addresses in prod. In dev, sure, for testing. If you change your IPs once in prod it becomes unwieldy. Use DNS. In your case: you haven't stated the hostname you're using so we assume it is colliding with the public DNS namespace. Change your hostnames to a private namespace or if you must use FQDNs in the public namespace, put entries in `/etc/hosts`: ##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
