Pihole stopped working after years

Help
1

Expected Behaviour:

Access to websites through DNS resolution. Running Debian 12, Pi-hole v5.18.2, FTL v5.25.1, FritzBox 7590

Actual Behaviour:

The PiHole cannot resolve any dns requests from clients or itself. I have tried pihole -r and it fails (Status: Connection Refused) .
After reinstalling it works but only for an Hour after that only my PC continues to Work
I can access the web gui ,ssh into the pihole and ping/dig external services.
resolv.conf points to itself. Changing the Nameserver won't work either
I really don't know anymore.

Please upload a debug log and post just the token URL that is generated after the log is uploaded by running the following command from the Pi-hole host terminal:

pihole -d

or do it through the Web interface:

Tools > Generate Debug Log

If this will not upload the log, then

This will temporarily reset the nameserver on the Pi to bypass Pi-Hole DNS.

sudo nano /etc/resolv.conf

Edit the nameserver line to nameserver 9.9.9.9 or your preferred third party DNS service, save and exit

Run

pihole -d

and upload the debug log.

Changing resolv.conf does unfortunately not work for the Debug command.
Using dig it shows that it changed the DNS but the pihole does not acknowledge it.
I tried resetting the Pihole and it works for about an Hour until it doesn't.
