The issue I am facing:
I've read trough a lot of information and tried a few things, but i can't get other devices to use pihole, it only blocks for the pi itself. I have apache2 and lighttpd running at the same time and switched lighttpd port to 8080. I added my devices (notebook, phone) in pihole, they are in default group. I changed the DNS in the devices to the Pi's IP. I tried to read trough the debug log and find a reason, but i'm failing. For now, i don't want all devices on my network to use pihole, that's why i haven't changed anything in my router. I also tried to use apache2 instead of lighttpd for pihole, but failed.
My debug token: https://tricorder.pi-hole.net/8crql4ep7g
Details about my system:
Raspberry Pi 4, Raspbian OS, Apache2 (Port 80, 443) and lighttpd (Port 8080) webservers running.
FritzBox 3490 router.
What I have changed since installing Pi-hole:
Changed lighttpd port, because 80 was blocked. Added my devices via group management.
Thanks in advance for any hints on what to try!
