I'm seeing a very similar problem, except I'm using a PPTP tunnel. I'm on a Mint MATE 18.1 distro. On approximately 3/8/2017 the network manager package was updated and about that time is when name resolution stopped working when connected to a PPTP tunnel.

I can see that the ppp0 interface is getting a DHCP address from the remote end, and it is also receiving a DNS IP address for the remote network. That information gets populated into 'etc/ppp/resolv.conf' and the timestamp for that file corresponds to the date/time I establish the PPTP connection.

I am able to reach machines on the remote network by IP address. This worked as of last week (approx 3/8/2017) and had been working for a year or more prior.

I'm not sure how the local resolver stuff works, but it seems like the proper information is being retrieved from the remote end point (IP address, DNS info, etc.), but the local resolver is not pulling in the information.
