VPN not working via Network Manager

[cesera]

I am trying to set up a VPN connection via Network Manager and it keeps timing out with the following log entries:

Jul  5 21:08:07 zaphod NetworkManager[32732]: <info> Starting VPN service 'openvpn'...

Now, when it was trying to connect I ran the following command with the following result:

~$ ps -ef| grep openvpn
root       963 32732  0 20:58 ?        00:00:00 /usr/lib/NetworkManager/nm-openvpn-service
root       966   963  0 20:58 ?        00:00:00 /usr/sbin/openvpn --remote my.vpn.server --comp-lzo --nobind --dev tun --proto tcp-client --port 443 --cipher AES-256-CBC --auth-nocache --syslog nm-openvpn --script-security 2 --up /usr/lib/NetworkManager/nm-openvpn-service-openvpn-helper --up-restart --persist-key --persist-tun --management 127.0.0.1 1194 --management-query-passwords --route-noexec --ifconfig-noexec --client --ca /path/to/my/certs/ca_cert.pem --cert /path/to/my/certs/usercert.pem --key /path/to/my/certs/userkey.pem

Now the strange thing is that when I take that exact openvpn command and run it manually (prefixed with 'sudo') it works every single time, however via Network Manager it always times out.

Any idea what is going on here?
