My VPN browser is not connected to the Internet

My VPN web browser is not connected to the Internet

First, I’m an Avast user and not an Avast Team member.

You have posted in the General Sub-Forum, so no clues there.
You are going to have to be a little more detailed, What VPN Web Browser ?

I don’t believe Avast has a VPN integrated into the Avast Secure Browser (but I don’t use that).

What Avast Antivirus program do you have ?
Whilst Avast One antivirus has a VPN component, it isn’t integrated into your browser, but part of the Avast Program.

Are you getting any errors displayed to the screen and if so what ?
