Running pihole on OpenWRT using docker with wireless interface

I was following this guide on how to install pihole on openWRT:

The difference with my setup is that I want the pihole container to be accesible from the WIFI interface. I could follow the guide and the container itself is running without errors, the problem is that I can't ping the container. In the screenshot you can see my network settings.

I assume the problem is here because I get an error on the interface

I have also found that you cannot use an ifname in the networkconfig on wireless interfaces and that you must add it in the wireless config, so i did that but with no result. (have changed nothing in /etc/config/network)

Now I have no idea how to move forward, can anyone help me?
I'm running openwrt 22.03 on a RPi 4 8Gb

Thanks in advance!
