Resolution: Follow the steps below to use default cipher suite list,

  1. Go to “Start > Run“. Enter: gpedit.msc
  2. In the left pane, expand “Computer Configuration > Administrative Templates > Network > SSL Configuration Settings“
  3. In the right pane, right click “SSL Cipher Suite Order” and choose “Edit”
  4. Save the text inside “SSL Chiper Suite” field to a Notepad for backup
  5. Select “Not Configured”
  6. Click “OK”
  7. Restart the server (gpupdate does not enforce this setting. Restart the server)

Note: If the setting is already "Not Configured", change it to "Enabled" and restart the server. It should work. Later, change it back to "Not Configured" and restart again.
