After updating to V4, my pihole stopped blocking ads. The web interface shows FTL: Offline. The following cmd shows:
sudo systemctl status pihole-FTL.service
Active
sudo systemctl status dnsmasq
Active (I do use dnsmasq)
I have also tried pihole -r several times with no success. FTL still shows offline. Looking at the FTL github, there's a note saying v4 FTL includes it's own dns and dnsmasq cannot be run at the same time?
Please note that we do not use dnsmasq any more as the process pihole-FTLincorporates the most recent version of dnsmasq now. You should stop dnsmasq and never look at it again. Everything you did with dnsmasq before will now work with pihole-FTL.
Both provide DNS service and hence both processes need to bin to port 53. This is probably the issue you're seeing. Try
Noticed the same on a 4.0 installing running in a Debian VM. Would run for approx ~24 hours or, then WenUI shows “Lost connection…”. Restarting FTL fixes it temporarily.
