Expected Behaviour:
Pihole works normally after update, able to resolve DNS addresses.
Actual Behaviour:
After running pihole -up, it will not resolve DNS addresses. I can't tell if there's an issue with dnsmasq or FTL. The web GUI reads Lost Connection to API in the 4 differently colored status boxes.
I had to manually update /etc/resolv.conf to change 127.0.0.1 to a different DNS just so I could get the debug to upload since apparently dnsmasq isn't working.
One other thing to note -- i'm running pi-hole in an LXC container on an Intel NUC, it's been working great for 2+ years, this is the first issue I've had.
