Hi, my pi-hole runs on a Raspberry Pi Zero W with Raspbian 10. In my Fritzbox 7490, the pi-hole is configured as primary DNSv4 server and DNS over TSL is activated. Until recently, everything worked like a charm. Things changed after updating my router.
Usually, I update the pi-hole via SSH using
sudo apt-get update && sudo apt-get upgrade -y && pihole -up
Currently this is what happens:
Temporary failure resolving 'raspbian.raspberrypi.org'
unable to access 'https://github.com/pi-hole/pi-hole.git/': Could not resolve host: github.com
Retrieval of supported OS list failed. dig failed with return code 10.
Unable to determine if the detected OS (Raspbian 10) is supported_
I tried uploading the debug token, but this didn't work either:
curl failed, falling back to netcat for transmission.
nc: getaddrinfo for host "tricorder.pi-hole.net" port 9999: Temporary failure in name resolution
Help would be appreciated.
