It’s the hosting account password, which I suggest you to change from the Client Area by logging into it, going on the hosting account you’re experiencing the problem, clicking on “Account Change” and then “Update Password” if you agree to generate it randomly (or fill in the “New Password” field with the new password you want to apply on the hosting account before clicking that button) instead of changing it through the Control Panel directly, as the latter can ruin the sync between Client Area and Control Panel.
