I installed Viber on my Ubuntu. It works fine until I reboot the system. When I power off my laptop and turn on laptop again Viber does not connect to the internet even though I have internet connectivity generally. I have downloaded the official version of Viber from https://www.viber.com/en/download/. I downloaded the .deb file for Ubuntu. Also I get two Viber pop-ups when I reboot the system even though I have installed only one.
