- 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 runexample(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
Dropping back to version 2021.12.1 resolved the issue
