Expected Behaviour:
Fresh install after trying to install DoH using cloufared (which broke pihole).
Actual Behaviour:
Pihole not installing. Can’t get DNS service running, FTL seems to have problems too. Tried -r a few times, rebooted a few times, removed every trace of DoH that I could find.
I don't normally offer this as a first solution, but it may be quicker to reimage the OS and install Pi-Hole from scratch again. When software installs go south, it can be very time consuming with the back and forth on a support forum such as this to pinpoint and fix the problem. If you don't have significant other software installed, this may be your quickest return to a functioning Pi-Hole.
