The log suggests all sorts of connectivity problems around the time that VPN Mgr notices the connection has gone away (no surprises there). There's nothing there to show you needing to run the wizard - I'd want to see that log too, with debug switch on.
You're also running a bunch of banned addons. If you want support to determine why the system is crashing (which I'd suggest is your biggest issue), you'd need to remove those and get a log with this behaviour in without them enabled. This probably needs it own thread.
Ok, thanks for all the advice Zomboided. It's a shared machine so I'll try to wipe it so it's just openvpn and will report back
