Depending on whether you can access the Norton website after you turned off the firewall, select one of the following:

I can access the Norton website only after I disable the firewall

If you can access the Internet after you disable the firewall, then you need to reset the firewall rules. For more information read Fix the connectivity problem if you can connect to the Internet only after disabling the Norton firewall.

If you cannot connect to the Internet even after you disable the firewall, uninstall and reinstall your Norton product. For more information, read Fix the connectivity problem if you cannot connect even after disabling the Norton firewall.
