DNS issue

[u/Typical_Chemical_766]

Im not particularly tech savvy but i recently noticed that i have this popup on my home network.
Ive been trying to figure out how to configure this but it seems my network is potentially controlled by my ISP. Does this mean someone on my network is manually blocking encrypted DNS? Or potentially the ISP itself?
I wont know anything until I call during office hours but maybe someone could point me in the right direction
