Resolved mine for the moment. It appears that maybe the TP LInk app has been updated? Even though my other devices were still working, uninstalling the app and reinstalling it seems to have worked...

@randerson0248 Just wondering if you resolved this or if your H200 was faulty.? I have the same issue. H200 and 2 x cameras working fine for 1 week. All of sudden the cameras showed as not connected...
