After turning off L2TP VPN connection, I'm having System reported and Error dialog. Please check logs form var/log/syslog. Also I'm not sure if this is related but Google Chrome remembers VPN location and keeps default search page related do this location (changing default search engine is Chrome settings fix this issue). Running Ubuntu 16.10.
I'm pretty new to linux. Any idea what's the root cause of the problem?
