"FTL offline" and "Lost connection to API"

First:
I installed this rpi2 at my home, it was working fine and doing two jobs:
updating ddns on my "own" server and running pi.hole
I made just one modification, moving logs to a connected USB-Stick.
I tried it at home, with several times rebooting and everything was fine.
Yesterday I installed it to my mums network and now it's not working anymore. (just the pi.hole)

Everything I've found to this error didn't help! That's why I'm writing here now.

THNX for helping!

Debug Token:

[Replace this text with the debug token provided from running pihole -d (or running the debug script through the web interface]
Here it is:
=====================================================
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.

It's easier when you just post the token, not the whole log, so people don't have to scroll a ton ;).

Run sudo service pihole-FTL restart

All right ...
but ... sadly ... it keeps the same, FTL still offline. :frowning:

Your log shows FTL as active... can you run through the debug steps listed here:

When I started and it's written that I should kill the process I got the feedback, that there's no process like this running ...
all right, ok the debugging ends with:

Check this issue:

You can try running these steps (from the issue):

sudo rm /usr/bin/pihole-FTL
sudo pihole -r

Sadly ... nothing helps :frowning:
i'm nearby setting up a new SD-Card and switching it.

Just tried to repair and reconfigure with pihole -r ... got this nice meage:

What is the output of sudo service dnsmasq status

Try sudo service dnsmasq restart and then pihole -r

It seems I am having the exact same issue as @synth here. My pihole is updated automatically via cron every Monday morning. This morning, some things were not working as expected. I logged in to pihole to see FTL not running. Tried to manually upgrade using -up. Did a dist-upgrade just to be sure. Tried the things described in this thread. FTL remains stopped.
My debug token is 7q3x89kv4v.

looks everything fine ... just
[βœ—] Backing up index.lighttpd.html
No default index.lighttpd.html file found... not backing up

and still no FTL offline and no API-Connection

I am also having this issue this morning. I get no local name resolution on the server either until I went into /etc/resolv.conf and set the dns to 127.0.0.1. For some reason it was set to my gateway IP address? I ran a pihole -up and it messed up the resolv.conf again and broke the API like above. I restored from backup and got them working and won't touch them until i see some options here.

Make a new debug token.

It looks like the core repo didn't update. What is the output of pihole -up?

@Mcat12 Thanks a lot for taking a look at the debug. I manually ran -up again and indeed, that looks like what causes the problem for my install:
pihole -up
