Can't access Pi-Hole web UI

[Melistraza]

Web UI of Pi-Hole not available!

I even added ports

    ports:
      - "53:53/tcp"
      - "53:53/udp"
      - "67:67/udp"
      - "80:80/tcp"

My docker-compose.yml file

Maybe I missed to uncomment some line?

bump, I have the same problem

[Vinl0c]

Same here, can't access the pihole webinterface with the same config

[rahul1996pp]

you have to use different host port to access for example
ports:
- "1021:80/tcp"
So you can access with your ip:port

you have to use different host port to access for example ports: - "1021:80/tcp" So you can access with your ip:port

even still can't access the pihole webinterface.

[Nezteb]

Just to double check, are y'all connecting to Wireguard first before attempting to access Pi-hole?

Connect to WireGuard [first] and [then] access the Pi-hole admin pane

If you try to access Pihole without first connecting to WireGuard, you'll be unable to because the container exposes no interfaces/ports.

Same issue for me. I have also added the ports to the pi-hole section of docker-compose.yml but still doesn't work. And yes, I am connected to Wireguard too.

@Nezteb
I am having the same problem.
Changing port 53 was mentioned in the aforementioned solution, but I turned it off because I get an error that it is already in use.
Naturally, we first connected to Wireguard and checked access to the piHoleGUI.
