Unbound failed to start after boot

[sarkyscouser]

I am running 23.7.5 on a N100/i226 mini PC.  I have a pppoe WAN connection (FTTP BT, UK). At boot the unbound service isn't starting, here are the relevant logs filtering for "unbound":

I don't have any domain overrides and I am using DNS over TLS for forward to 2x ipv4 upstreams and 2x ipv6 upstreams.

If I start unbound manually it fires right up and works but will fail on next reboot.

Just upgraded to 23.7.6 and restarted and unbound did start this time so it's hit and miss, what else can I do to diagnose?
