WireGuard VPN unable to see PiHole IP

I'm running PiHole in a Raspberry 4 8GB with Open Media Vault on a Docker Container. I installed Wiguard using pivpn and it works ok, I can see everything in my local network except the PiHole's IP admin GUI. The main issue is that since the IP is not recognized, I cannot route the internet traffic through it.

What is the URL you are using to access the web admin GUI? Also, please post a screen capture of what you see in the browser at that URL. Note - in this forum you can post an image directly into your reply.

Ok, so it seems that I was over complicating things. At the end I tried installing Raspbian/Raspberry Pi OS instead of keep using OMV as the operating system and installing Wireguard on top of it and PiHole inside a container.

Once I had Raspberry Pi OS up and running I installed the three with the install command for each one (WireGuard after PiHole so it can detect it), changed OMV Port to 81 so it didinĀ“t clash with PiHole and voila, everything worked.
