Hi,
I have Pi-hole with unbound running in a Docker container. A few times per day all smartphones in the network show "no Internet" for a few seconds to minutes and resume working as intended after that. The Desktop didn't experience any errors.
Expected Behaviour:
Phones stay connected.
Actual Behaviour:
periodically all phones (only android, iOS not tested) show "no internet" and switch to mobile data for a few minutes
Tested:
Changing the DNS server in Pihole from unbound to 8.8.8.8
- same result
Changing the DNS server in the DHCP settings of the router to 8.8.8.8
- issue is gone
Further information:
Querry log of Pi-hole doesn't show any related blocked querrys
Diagnostics is empty
