FTL is Offline nothing obviously wrong with config

General

Probably similar to other people's problems, but haven't found a solution. I don't belive I did an update, upgrade or reboot. I am unsure what caused the problem. I only noticed by accident that PiHole was having problems. My pihole is not the DHCP server, has a fixed IP address. This does not seem to be causing any problems with network devices navigating.

First my FTL was offline and Lost Connection To API was showing. Then I discovered that the DNS was missing so I forced it to 8.8.8.8. That allowed the sudo pihole -r to work and to download its update. DNS servers now show as:

pi@raspberrypi:/var/log $ nslookup www.google.com
Server:         127.0.0.1
Address:        127.0.0.1#53

Non-authoritative answer:
Name:   www.google.com
Address: 216.58.205.68
Name:   www.google.com
Address: 2a00:1450:4002:807::2004

At this point I have "Lost --- --- API" across the top of the dashboard and all the graphs are spinning circles. I have tried:

  • repair and a reconfigure options but neither fix the problem.
  • rebooting and restarting services, flushing logs and network tables

The pihole-FTL.log is https://pastebin.com/HYb72C0E

Not sure where else to try. I followed the guide to install screen and gdp. GDP was already installed and screen doesn't seem to do anything. maybe I misunderstood something.

Any ideas what to try next?

Thanks!

Your successful nslookup from your Pi-hole machine would imply that Pi-hole is working (i.e., if indeed run from your Pi-hole machine, with Pi-hole being the only process listening on port 53).

This would hint at a client browser issue.
Have you tried clearing your browser's cache?

Thanks for the suggestion. Clearing the cache has now showing Lost Connection To API across the top (changed from "---" on the two middle windows). Digging around in the suggestions on the forum, I note that http://192.168.1.xx/admin/api.php?overTimeDataForwards&getForwardDestinationNames returns

{

  • FTLnotrunning: true
    }

Please provide a debug token generated by

pihole -d

or do it through the Web interface:

Tools > Generate Debug Log

sorry, just to be clear, that nslookup was run from the pihole machine. /etc/resolv.conf has returned to only include localhost (8.8.8.8 has been removed by the machine)

DNS config page is set to only OpenDNS and all other checkboxes are unchecked.

You have another DNS server claiming port 53:

*** [ DIAGNOSING ]: Ports in use
*:3128 squid (IPv6)
*:1880 node-red (IPv4)
[53] is in use by named (https://docs.pi-hole.net/main/prerequisites/#ports)
[53] is in use by named (https://docs.pi-hole.net/main/prerequisites/#ports)
127.0.0.1:953 named (IPv4)
[::1]:953 named (IPv6)
[53] is in use by named (https://docs.pi-hole.net/main/prerequisites/#ports)

You'd have to disable or uninstall that other DNS server (likely that's BIND/named).

Interesting, seems that when I put webmin onto the pi, it (or I by mistake) started the bind dns server. stopping that has fixed the issue, thank you so much for your time!

You're welcome. :wink:

Could you do me a favour and tag an appropriate post as solution?
