AdminLTE version is v5.9 - php.socket-0 Connection refused

The warnings have always existed in /var/log/pihole.log. A change to Pi-hole made them more visible by also printing them into /var/log/pihole-FTL.log and showing them on the dashboard.

Brief documentation for these warning can be found here:
