As the title states i get this error when i open up the launcher, it was fine yesterday and nothing has been changed or installed since

Things i have seen on web and tried:
Reseting internet explorer settings to default.
Reseting lan config to automatically detect.
System reboot.
Router reboot


Any help please?
