There are times when the Connection may drop out, but when it comes back on line you still get all of the latest streaming updates.
Check the Statistics > Component status and see if you are still receiving streaming updates - Mine shows 365 in the last 24 hours. Yours are likely to be different but not by much given we are in the same time zone.
Fixed! I remember there used to be an option to repair, but it was not available this time. So, I uninstalled / reinstalled and connection is now established. People say that sometimes this happens, but my connection was showing not established for around 2 weeks, yet i was still receiving updates. Just not getting notified of them.
