I GET THAT ERROR, IN WINDOWS 10. IT IS IMPOSSIBLE TO BE ABLE TO ACCESS, I HAVE USED EXPLORER, CHROME, REMOVING AND PUTTING ANTIVIRUSES .... I DO NOT KNOW A LOT OF COMPUTERS, BUT I NEED IT TO WORK, I NEED HELP
Do you have Pulse Secure Terminal Services client installed on your machine? Go to Control Panel >> Uninstall program >> Look for it. Please uninstall and try to launch it from the browser and see if helps.
When did the last time you saw it working? Any changes like OS upgrade after that?
