I have had this problem since December.  I have now had three emails telling me it is fixed when plainly it isn't.  The last two came this morning.  I can logon to the account outside QBO using my old URL and also with the URL QBO is using.  So that can't be it.  My main frustration now is that I contacted the Helpdesk yesterday and spent about 30 minutes trying to communicate simply to say that the error had not been fixed.  I don't want to go through that again.  Stuart
