Unable to reconnect -- RESOLVE: Cannot resolve host address: [HOST]: Try again #5

I noticed the following today that the OpenVPN client was unable to reconnect when the session timed out. The the inactivity timeout occurred and the VPN connection was lost, the routes did not revert and still appear as though the VPN connection is established, which explains why it can't reconnect.

I would MUCH prefer that only the OpenVPN process have Internet connectivity when the VPN is disconnected, but it seems the routes definitely need to be reset/cleared after a timeout/disconnect in order to restore connectivity for a DNS lookup and reconnection.

Alternative: Kill the container when OpenVPN disconnects/terminates and let Docker restart it?

I found a similar issue with dperson's image and I'm wondering if the same might apply? https://github.com/dperson/openvpn-client/issues/13

Are you pushing a DNS server to the client, that exists over the VPN tunnel?
