  • Uncheck the proxy tab and click on ok.

After removing the checkmark from the proxy tab, you should also check the program and features.

ensure that, there is no third-party VPN or proxy application running into the computer.

Time And Date Issue- 

Do you know, the time and date play a very important role in maintaining a secure connection. if you have the wrong time and date, it will not work for you and create lots of problem for you.
