Specifically it's your configuration.  You are hardcoding an IP
address to bind to, thereby telling nginx to not start until that IP
is active.

That will prevent nginx from staring in situations where systemd
determines that the external network is not yet active (dhcp, etc.,
etc), yet nginx may still run perfectly fine with split interfaces,
localhost, etc.
