DHCPv6 pid file for monit? Correct service command? (won't start at boot)

[mike8971267]

Hey all,

I'm having an issue lately where the DHCPv6 server (for the lan) doesn't start at boot anymore. I need to manually start the service via the Web GUI. Once started, DHCPv6 seems to work on my network again.

I cannot figure out how to force it to start at boot, nor how to get monit to ensure it is always up. I've made several attempts to get the server to use a PID file for monit, but it never shows up.

Additionally, the service `service isc-dhcpd6` doesn't seem to be connected to the same service that the web GUI starts. When I use `service isc-dhcpd6 start`, it is not reflected in the web GUI. When I use `service isc-dhcpd6 status`, it claims the service isn't running even after being started via the web GUI.

Help please :'(

My dashboard showing DHCPv6 did not start at boot:

In this final screenshot, I've started DHCPv6 via the web GUI then asked via CLI whether it is running. You can see the command thinks it is not running, and there is no PID file to be found either:
