I haven't had this one yet but I did have the "party leader has disconnected" bug. Which I got rid of by deleting the Origin cache.

You could also run Origin as admin.

There is a thread here on the same topic.

You could also try enabling or disabling UPnP on your router. This is a setting which has stopped me connecting to games in the past, depending on how it's set.
