Pi-hole admin page cannot be reached

Expected Behaviour:

Type in the browser address bar 192.168.1.197/Admin and see the admin page

Actual Behaviour:

Unable to connect

Debug Token:

https://tricorder.pi-hole.net/5rgeze8yzs

The debug says “No IPv4 address(es) found on the interface.”
WTF? How am I able to connect to it via SSL, using that IP, then???

This is not specifically a Pi-Hole problem, it is a problem with the host platform for Pi-Hole (in your case it appears to be a Pi) not having an IP address that leads to the router.

*** [ DIAGNOSING ]: Networking
[✗] No IPv4 address(es) found on the  interface.

[✗] No IPv6 address(es) found on the  interface.

[i] Default IPv4 gateway: 192.168.1.1
   * Pinging 192.168.1.1...
[✗] Gateway did not respond. (https://discourse.pi-hole.net/t/why-is-a-default-gateway-important-for-pi-hole/3546)

Your Pi-Hole is configured to listen on 192.168.1.197, and if it receives traffic there, it is responding properly. You can confirm the IP setup of the Pi with this command from the Linux terminal:

ip addr

The second problem is that the lighttpd daemon is failed, and this is the server that provides the web page.

*** [ DIAGNOSING ]: Pi-hole processes
[✗] lighttpd daemon is failed
[✓] pihole-FTL daemon is active

*** [ DIAGNOSING ]: Dashboard and block page
[✗] Block page X-Header: X-Header does not match or could not be retrieved.

[✗] Web interface X-Header: X-Header does not match or could not be retrieved.

What are the outputs of the following from the Pi terminaL

sudo service lighttpd status

sudo systemctl status --full --no-pager lighttpd

A third potential problem is this section of your debug log - either the output is corrupted in the log, or you have some domains included in your setup file (which is not where they should be).

Check the following files: /etc/pihole/setupVars.conf and /etc/pihole/pihole-FTL.conf

The OrangePi has an active IP address (192.168.1.197), and that’s what I use to log in via SSH.
Also it has Internet connection because I could install the Pi_hole via Internet (plus updates for the Armbian).
ip addr shows:


root@orangepione:~# ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo

    inet6 fe80::1714:7ec3:4a8e:dafc/64 scope link
       valid_lft forever preferred_lft forever

So to it looks like just the PiHole that doesn’t “see” that connection.

Run pihole -r and make sure to choose the correct interface.
