Re: Networking failing using openvpn

A big problem is that the server you are showing doesn't exist any more (142.103.194.4). We need to figure out why that is also. Somewhere,  that ip is hard coded.

Sounds like openvpn is losing the gateway, and not able to recover.

This is probably because your DNS 1.1.1.1 is not accessible after the tunnel drops. With DNS dead, your node will not be able to lookup vpn01.irlp.net.  I would suggest using your local router for DNS (not 1.1.1.1 or other outside nameserver).  The reason is that your local router will always work regardless of the VPN being there or not.

I would also recommend upgrading to Debian 9 Stretch.  The version of OpenVPN that comes with 9, is much more robust than Debian 7.
