Log extract of VPN connection being dropped and restarted repeatedly
Description of problem:
When connecting to this openvpn, the connection continually drops and restarts every 10 to 20 seconds. This disrupts SSH attempts to the machines accessible through the VPN.
The /var/log/messages file gets filled with the attempts, including messages such as:
Oct 14 17:37:44 avillacis dbus: [system] Rejected send message, 3 matched rules; type="method_call", sender=":1.183" (uid=982 pid=16826 comm="/usr/libexec/nm-openvpn-service-openvpn-helper --t") interface="org.freedesktop.NetworkManager.VPN.Plugin" member="SetConfig" error name="(unset)" requested_reply="0" destination="org.freedesktop.NetworkManager.openvpn" (uid=0 pid=16716 comm="/usr/libexec/nm-openvpn-service ")

I see no weird messages in audit.log (extract attached).
Setting "setenforcing 0" has no effect. The connection keeps being dropped and restarted.
I have not modified any dbus files under /etc. Just in case, I will post their contents.
