I have been having a rather serious and incredibly annoying problem on the updated version of network-manager v1.2.6 in Ubuntu 16.04 LTS. Trying to manually connect to my VPN provider through the network manager openvpn client fails literally any time except bootup. Every godforsaken time. Waking the computer from suspend results in the network manager 'reconnecting' but no actual internet connection. Restarting the network manager using
sudo service network-manager restart
sometimes doesn't work at all and I actually have to reboot the computer for it to connect to the internet. Despite the icon showing that I'm connected, in actuality I have no internet connection and cannot load any web pages. This issue isn't present at all on v1.2.2, which I have downgraded to and used apt-mark hold to keep it in place. Any insight or confirmation of this issue would be appreciated.
