The issue I am facing:
Full error: There was a problem applying your settings. Debugging information: PHP error (2): fsockopen(): unable to connect to 127.0.0.1:4711 (Connection refused) in /var/www/html/admin/scripts/pi-hole/php/FTL.php:43"
After maybe 5-10 min, pihole gives "dns server not running," status. Rebooting resolves for a few minutes each time.
Details about my system:
Pi3b, Raspbian 11, PiVPN, Unbound, Homebridge
What I have changed since installing Pi-hole:
Fresh pihole install with new SD card. Had an issue with a full SD card because of logs, couldn't get any logs to flush so I grabbed a different SD card and fresh installed everything. Thats when this issue began.
Can't find anything using port 4711, not knowledgeable enough to resolve myself after scouring the internet for help.
Your debug log doesn't show any PHP errors and it shows that port 4711 is being used by pihole-FTL as we expect.

I saw the error at the top of the settings menu.
More issues have developed so I’m trashing this install and starting over again. This topic can be deleted.
Thanks.
