So I just install a version 7.12 CHR on my laptop. I created a virtual interface where I installed Pi-Hole on a container. It works, I can enter to the shell and it's running, but when I configured the port forwarding rules and I try to access to the admin web page it shows a welcome page and says that the administrator hasn't uploaded nothing yet.

My hAP ax Lite IP address is: 172.16.0.1/24
My Laptop IP is: 172.16.0.5/24
My CHR installed on winbox on my Laptop IP is: 172.16.0.4/24
The bridge interface for my containers is: 172.16.1.1/24
The veth1 interface where my Pi-Hole is installed is: 172.16.1.2/24

Also, when I ping my hAP ax from my Pi-Hole shell I get replies, but when I try to ping my CHR from my hAp ax or my laptop I get no reply. What should I do? Help me pleaaaase por favooor ayuuuudaa.

Add “/admin” to the URL. This is a well-known upstream issue, not something for us to fix here on the RouterOS side.
