Actual Behaviour:

Lost Connection to API. I have tried to resintall, restart FTL service and systemctl settings as seen in other topics but no luck. Any chance some one could look at my token if I am missing something obvious

Doesn't look like FTL is even running?

That is correct FTL showing as not running. Unable to manually start it even after a reboot.

After such a failed restart, what's the output of:

sudo systemctl status --full --no-pager pihole-FTL.service

Here is the output

That's your issue.

What's the output of:

grep -nRv '^#\|^$' /etc/dnsmasq.*

here is that output

Not one of Pi-hole's files, probably empty.
The following command would confirm this.

ls -lah /etc/dnsmasq.d/lxd

If you don't run lxd containers, you may delete that file and then run

pihole restartdns
