[SOLVED] Pi-Hole showing 0 queries

EDIT: (solution see below)

I don't think pi-hole is picking up any of my computer's requests (shows 0 queries, 0 blocked etc... on the pi-hole admin page)

My docker-compose.yml (Note port mapping 8080:80):


 version: "3"
 
 # More info at https://github.com/pi-hole/docker-pi-hole/ and https://docs.pi-hole.net/

     # Volumes store your data between container upgrades
     volumes:

       - './etc-dnsmasq.d/:/etc/dnsmasq.d/'
     # Recommended but not required (DHCP needs NET_ADMIN)

     cap_add:
       - NET_ADMIN
     restart: unless-stopped

I've set up my wifi connection DNS address to my raspberry pi IP by following these instructions:

Linux

In most modern Linux distributions, DNS settings are configured through Network Manager.

  1. Click System > Preferences > Network Connections
  2. Select the connection for which you want to configure
  3. Click Edit
  4. Select the IPv4 Settings or IPv6 Settings tab
  5. If the selected method is Automatic (DHCP), open the dropdown and select Automatic (DHCP) addresses only instead. If the method is set to something else, do not change it.
  6. In the DNS servers field, enter your Pi's IP addresses
  7. Click Apply to save the change
  8. Repeat the procedure for additional network connections you want to change.
  9. If your distribution doesn't use Network Manager, your DNS settings are specified in /etc/resolv.conf .

Generate debug log output:

This process collects information from your Pi-hole, and optionally uploads it to a unique and random directory on tricorder.pi-hole.net.

The intent of this script is to allow users to self-diagnose their installations.  This is accomplished by running tests against our software and providing the user with links to FAQ articles when a problem is detected.  Since we are a small team and Pi-hole has been growing steadily, it is our hope that this will help us spend more time on development.

NOTE: All log files auto-delete after 48 hours and ONLY the Pi-hole developers can access your data via the given token. We have taken these extra steps to secure your data and will work to further reduce any personal information gathered.

    * The debug log can be uploaded to tricorder.pi-hole.net for sharing with developers only.
    * For more information, see: https://pi-hole.net/2016/11/07/crack-our-medical-tricorder-win-a-raspberry-pi-3/
    * If available, we'll use openssl to upload the log, otherwise it will fall back to netcat.

    * Log will NOT be uploaded to tricorder.

Any ideas? Thanks :slight_smile:

SOLVED: So the solution was really to set the docker port to 80:80... I just had to take down my other application that was using that port.
