Cisco Umbrella Block

I am running Windows 11.  Acrobat DC was Wiorking fine.  Then It updated to Pro (School Account).  Now every time I try to start Acrobat, I get a large white box that says cite blocked (ims-na1.adobelogin.com) from the Cisco Umbrella.  I tryied the registry patch AdobieAcrobat_PMOff.  It didn't help.  Any ideas.
