For me it worked after windows update.

  1. Go to settings then update & Security.
  2. Click on check online for updates from Microsoft update -> It will start downloading the updates and will installing automatically.
  3. once installation and downloading completed it will ask for restart then go for restart the system and then try.

1- Select your site in IIS.
2- Go to top-right and click on bindings.
3- Select your application and click edit.
4- Select a SSL certificate, if it doesn't exist then you may need to create
it.
