I am trying to set up a new Debian 10 build server, and the first step is
gaining the ability to ssh into the device from outside my local network.
For whatever reason, this is proving to be difficult and I haven't the
slightest clue why. When I try to ssh into my server with user@hostname, I
get the error:
ssh: Could not resolve hostname {hostname}: Name or service not known
When I try to ssh into my server with user@IPADDRESS it's successful
ping {hostname} : ping: {hostname}: Name or service not known
ping {IP}: successful
nslookup {hostname}:
;; Got SERVFAIL reply from x.x.x.x, trying next server
Server: x.x.x.x.
Address: x.x.x.x.#53
** server can't find {hostname}: SERVFAIL
nslookup {IP}: successful
Ansible Playbook:
- hosts: buildservers

I'm trying to run ansible role on multiple servers, but i get an error:
fatal: [hostname]: UNREACHABLE! => {"changed": false, "msg": "Failed to
connect to the host via ssh: ssh: Could not resolve hostname hostname: Name
or service not known", "unreachable": true}
