Comment 11 for bug 1767322

I am seeing this issue as well.

I have two networks that are both configured to join a VPN, and when both networks (wifi and wired) are activated simultaneously, I see a message:

    Aug 21 15:45:58 example NetworkManager[1196]: <warn> [1534823158.7630] policy: secondary connection 'Example (12345678-1234-1234-1234-1234567890ab)' auto-activation failed: (6) Connection 'Example' is already active

So - the fix for me is to disable (manually, currently) the wifi when my laptop is docked; this seems to allow the VPN to connect on the (sole remaining) network connection.

Posting in the hope this might help others, and to follow along with this issue :)
