Failed to update Android SDK package list - 2020.3.8f1

It keeps giving me Can’t Update the SDK package list. Unchecking and Relaunching does NOT work. I do not have Android Studio installed, and Unity says everything is installed. I have spent hours trying to find a solution and nothing works!!

This is still happening to me blocking my project, this is with everything on the latest so 2021.2.8f1
I am looking at the effort of porting my project to Godot Engine, the effort of fighting constant bugginess of Unity starts to look like more effort than a full port.
