pigpio: "socket connect failed" but only if starting pigpiod via systemctl

Not sure if I’m using it wrong but I can’t seem to get pigpiod working if I start it as a service via systemd. Log of my actions as follows:

Made sure pigpiod was not running and then started it via systemctl:

pi@rpi-robot:~ $ ps aux | grep pigpiod
pi        1381  0.0  0.5   4364  1912 pts/0    S+   14:47   0:00 grep --color=auto pigpiod

pi@rpi-robot:~ $ sudo systemctl start pigpiod

pi@rpi-robot:~ $ pigs hwver
socket connect failed

Noticed that it seemed to have only bound to the ipv6 address ::1?

Killed that version and started up via sudo and it works fine. Notice how the bind address is different but the port (8888) is the same

This is pretty much a fresh install of Raspbian Lite 9 (Stretch) on a Pi Zero W.
