Troubleshooting, not sure what is wrong or where to start

Expected Behaviour:

operating system Pi-OS

Hardware Raspberry pi 3 B+

Actual Behaviour:

gateway did not respond IPv4

Error NTP client: cannot resolve NTP server address: try again

Debug Token:

it failed to upload the log, I’m not sure what to do about that.

I have no idea how to fix this. It was working for a min before I tried to change the router DNS address to the pi-hole. And now I am stuck and feel like I don’t know enough about how this works to start fixing it.

What was the message that was printed out when it failed to upload?

3

Curl: (6) could not resolve host: tricorder.pi-hole.net

There was an error uploading you debug log.

Okay, that looks like there is no working DNS on the Pi-hole server itself.

Can you edit the /etc/resolv.conf file and make sure there is a publicly accessible DNS server listed there, like 1.1.1.1 and then run pihole -d again please?
