Hi @JohnBoy. Thanks for being part of GoDaddy Community! Sometimes this issue is due to other settings you might be using. First, make sure you're using your full email address any time you're entering your username. If that isn't the issue, consider providing screenshots here of the settings you're using. That may help the community offer suggestions.
