I'm running pihole and doh from cloudflare on my pi and installed openvpn yesterday and for some reasons the pihole stopped working (requests from my devices are not delivered to the pi hole and do not show up in the querly logs). I played a lot and now in the query log there are the requests of my devices, but with status unknown and replay N/A, so tried to fix this and now for some reasons pi hole shows:
DNS Service is not running, FTL not running.
