Comment 10 for bug 117992

I've spent half an hour debugging same problem and I vote for 60seconds timeout as my server logs show following:

TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity)

where 60 equals handshake_window from openvpn-2.0.7 soruces.
60 seconds is default openvpn setting and I assume that network-manager-openvpn should use it.
