to me, it looks configured correctly. I suggest you open a Support case, mentioning what you've tested so far. (You might want to refer to this thread as well, so that the Support engineer does not have to start from scratch).
the support portal has been migrated to a new system recently. If you haven't opened a ticket in the past 4 weeks or so, it is necessary to reset your PW. Please use the "forgot my pw" option. Thank you for your cooperation!
