I just hope i am not missing any configuration parameters which is causing this.

These common fixes didn't work for my issue

  • I have tried removing/destroying my container, and re-creating a new container
  • I have tried fresh volume data by backing up and moving/removing the old volume data
  • I have tried running the stock docker run example(s) in the readme (removing any customizations I added)
  • I have tried a newer or older version of Docker Pi-hole (depending what version the issue started in for me)
  • I have tried running without my volume data mounts to eliminate volumes as the cause

If the above debugging / fixes revealed any new information note it here.
Add any other debugging steps you've taken or theories on root cause that may help.
