I had to turn VPN off to get to the Norton Support Website
Many web sites do not allow access from known VPN IP addresses. They do this for copyright, legal, security, and political reasons. There is nothing a VPN provider can or should do to circumvent these legal protections. See this How to Geeks article. https://www.howtogeek.com/403771/why-do-some-websites-block-vpns/
It seems Norton is one of those sites.
Maybe, Norton wants to know your true location.
