Problem with Software Updater

Using latest version v6.34, try to use Software Updater, the side button shows a red ‘2’, but when I click to open, it shows ‘no software updates available’. If I click ‘scan again’, get popup ‘an issue occurred - an unexpected error has occurred during the software update process - try again later - error code: 100’. This has been going on for over a week when I had v6.33, still going on after the update to v6.34.
