The browser only vpn worked fine, the paid version refuses to connect. I finally got to the point where I can see the (Opera VPN Service) connection but everytime I try to enter my credentials it says my credentials [username and password] are invalid. I know I'm entering them correctly, is there a step I'm missing here?
