I have installed pihole, in my rasberry pi from the command line, not docker. It works locally in the rasberry. And in fact it is blocking ADs in all my network. So it is technically working
However, I can only access the admin portal/dashboard on my localhost inside my rasberry pi. If I use ip/adming, it wont work.
Here are the logs
