I am affected by the same issue when I am connected to the office VPN. NetworkManager is using dnsmasq (as in /etc/NetworkManager/NetworkManager.conf).
If I comment out the line dns=dnsmasq in that file, things work fine, but I prefer to use dnsmasq. I have to restart the service every now and then when DNS resolution stops working :(. sudo service dnsmasq restart -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to dnsmasq in Ubuntu. https://bugs.launchpad.net/bugs/1652449 Title: dnsmasq requires restart randomly now and then in order to access random URLs Status in dnsmasq package in Ubuntu: Confirmed Bug description: I use dnsmasq along with a long list of domains blocked in order to prevent spyware, malware, etc. on my personal computer. I've begun having frequent DNS problems after upgrading my Ubuntu (64 bit) system from 16.04 to 16.10. From time to time a random URL address suddenly becomes unreachable with varying error messages, most common one that I remember is some sort of a DNS ERROR. I've found that the only remedy is this "sudo /etc/init.d/dnsmasq restart". After that, the problem disappears - for some time. Such URL addresses cannot be accessed system-wide until dnsmasq service is restarted, but they can be accessed via Tor Browser only, which bypasses dnsmasq I guess.
