I am getting Fatal Error with invalid host name for Kibana service because of server has host name starting with integer.

Any idea why Kibana service doesnt like host name starting with integer because as per RFC 1123, it should allowed it.

Kibana.yml

Maybe cannot do lookup. Would be better to use IP.

Set `server.host: 0.0.0.0`, that should help.
