I'm having what looks like the same issue ever since a W-10 Pro 64b update on Feb 12 or Feb 16     I can no longer login to this vpn on my W-10 PC.  I tried recreating the vpn 5 times with the same error message after a long negotiating attempt.  The same login information works on my W-7 laptop without fail.     I had changed no settings on the W-10 Pro 64b machine when the error began appearing.  I looked through all the 'fixes' listed in this discussion and cannot find a fix.  I've thought of trying to restore my Pc to a date earlier in Feb but have some other valuable data I don't want to lose.  HELP!! ...
