Welcome back to another easy fix!
If you are a Kaspersky user and you got an error says: Kaspersky cannot setup server connection, and your activation key is already active or not expired!, then don’t worry I am also faced the same problem and I will show you an easy fix with very simple steps:
type or search on your windows for word:”edge” which is Microsoft edge.
right-click on Microsoft edge icon and click on app settings, a new window will show with some settings and scroll down to Repair and Reset buttons click them and Restart you PC. and Finally you will not get the error: “Kaspersky cannot setup server” anymore!.
