the VPN must be turned off in order to do business with Duke Energy. FIX THIS ISSUE.
First, I’m an Avast user and not an Avast Team member.
I also don’t use any VPN, so I can’t speak from personal experience.
Some countries and companies actively block VPNs, it doesn’t allow them to track who the user is and location they are in. That said there isn’t much information on why this happens and what the error message, the country or issue is.
