Dns returning bad address for everything. Seemingly getting bad response from upstream DNS

General

pihole returns wromng address. For every domain, it returns 10.0.0.2. It seems to correct itself automatically. The upstream servers (google, OpenDNS) seem ok too. Here is log snippet where it corrected itself.

Please upload a debug log and post just the token 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

Thank you !

It seems my DNS resolutions fixes itself at/around 7AM. I ran debug before that time and the upload failed because it could not resolve tricorder.pi-hole.net. However I uploaded that log manually also afterwards. Here is the token for that.

I think I found the issue (just now). I had accidentally included the pihole mac address into nighttime block list (when trying to update kids' devices). That the DNS only failed between 11p-7am made it obvious in retrospect. You can please close this case.
Your work on this project is greatly appreciated !
