ArchLinux Pi-hole is not officially supported by Pi-hole project. In case of bugs and malfunctions please DO NOT file a report upstream.
First of all check if the wiki (https://wiki.archlinux.org/index.php/Pi-hole) can help then ask here for assistance and tips.
When it will be excluded that the problem does not depend on ArchLinux we will file a bug upstream.
