Current Pi-Hole: Unavailable

[VocifSky]

First off, this will be super helpful when I get it working, so I appreciate you putting this together.
Second, had installed pihole previously, manually, through Container Manager.
Third, used git to copy over script (v1.2.3) then ran under sudo and received the following. Not sure what else I can influence from command line arguments to get the script aligned to my synology/docker/pihole instance.

INFO: IP of synology (.10), pi-hole instance (.11). Container is pihole. Docker network for container is ph_network (macvlan). host is synofile, pihole is pihole on DNS. Full IP addresses redacted with 'x'.

~/synology-pihole$ sudo ./syno_pihole.sh --ip x.x.x.11 --host-ip x.x.x.10 --log ./logfile update
