Pi Hole messing up my networking

Please follow the below template, it will help us to help you!

I am running a fresh install of pi hole in a docker container, on my orangepi 3lts, a single board computer that I installed casa os onto

Expected Behaviour:

Websites such as:

to work, and load.

Actual Behaviour:

none of the listed sites work, everything else does work (ad blocking, youtube, google, discourse.pi-hole.net, etc...)
note - disabling adblocking does not fix the websites

Debug Token:

https://tricorder.pi-hole.net/4V0njxbN/

some things I noticed in the debug log:

*** [ DIAGNOSING ]: contents of /etc/lighttpd/conf.d
/etc/lighttpd/conf.d does not exist.

[✗] Failed to resolve doubleclick.com via a remote, public DNS server ([redacted ipv6 address])

[✗] No IPv6 address(es) found on the eth0 interface.

This is a clear indication that Pi-hole is not involved in the issue.

This is probably a network configuration, or an OS issue.
