The Linux Viber app can be quite problematic and very difficult to debug. There were many cases in the past of it misbehaving due to missing cryptographic or SSL libraries.

This is the single most useful solution I was able to find to the “No Network” issues.

Make the NetworkManager service use dhcpcd instead of nettools’ n-dhcp4.

Just modify /etc/NetworkManager/conf.d/dhcp-client.conf by adding.

[main]
dhcp=dhcpcd

Save the changes and restart NetworkManager. The (deb, Flatpak or AppImage) Viber app should now be able to connect.
