Hi there, there are some errors in Pi-hole: - when trying to save settings, “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 /snap/pihole/537/web/scripts/pi-hole/php/FTL.php:47” - syncloud offers an update for Pi-hole: When trying to apply that update: “cannot refresh “pihole”: Get “[http://apps.syncloud.org/releases/stable/index-v2](http://apps.syncloud.org/releases/stable/index-v2)”: dial tcp: lookup [apps.syncloud.org](http://apps.syncloud.org) on 192.168.178.46:53: read udp 192.168.178.46:39794-\>192.168.178.46:53: read: connection refused, url: [http://apps.syncloud.org/releases/stable/index-v2](http://apps.syncloud.org/releases/stable/index-v2)” ---

Looks like pihole is not running or having issues on the box and I guess it is set as a primary dns on your router so it does not allow any dns to be resolved properly. Usually you set pihole to be primary dns but also set a secondary dns to be some public dns in case pihole is not running. Also you can try removing pihole and installing it agiain to see if that helps.
