haproxy not starting on opnsense restart

[sos_opnsense]

On OPNsense 23-series and now 24 I have a problem where haproxy often won't come up when the system reboots.

Since I use haproxy to access a number of services via virtual servers (home assistant etc) it's a bit of a problem having to go into the dashboard and manually restart haproxy.

So - a couple of questions / requests for help:

1) Is there a reason for this behaviour?
2) Is there a way (cronjob, systemd service call) to automate ensuring haproxy is up, and if not, start / restart it?

In regards #2, under HAProxy > Maintenance, there is a 'Cron Jobs' tab, which can be used to reload or restart HAProxy. I'm wondering if one of the configurable parameters could be used to "restart HAProxy IF not running"?

Thanks!

EDIT: and I've just discovered on 24.1 under settings, Rules&Checks, User Management, Settings and Advanced are all blank! Despite this, my virtual servers are still working, so seems to be an error with GUI. Will open a separate thread.... - I'm an idiot...I forgot there are drop-down menus!
