If you are Experiencing issues with a Pi-hole install that has non-standard elements (e.g you are using nginx instead of lighttpd, or there is some other aspect of your install that is customised) - please use the Community Help category.
Expected Behaviour:
I'm using Ubuntu 22.204 with Gnome and Wayland. I expect Pihole to successfully start when I open Firefox, like it has for years.
Actual Behaviour:
When I open Firefox, Pihole is not working, no activity on the Pihole Dashboard. I get the error "unable to resolve host advait-Bravo-15-A4DDR: Name or service not known"
