Cannot Sign In to Norton 360 Acc from Laptop

I have just had cause to create a new user account (with a new name) in Windows 10 to correct a number of problems.  I create the new user and deleted the old one and Windows 10 is now working well but I am unable to sign in to my Norton 360 Account.

I select "Sign In" on the Norton 360 home page and a popup window starts headed Norton 360 Subscription.  The popup says that the software is communicating with Norton server but then it times out with a message that says "Cannot connect to the Norton server" and "Unable to contact the Norton server. Please try again."  I can try this multiple times but without success.  Can you please advise a fix.  Live update etc seems to be working correctly.
