Cloud Connector losses connection to the cloud without detecting it.

[DivineThreepwood]

Maybe this logs delivers some hints about the real issue. At least once the cloud connector detects the missing connection, those is successfully reestablished. Maybe we need just to activate TCP keep alive pinging to stabilize the connection.

Or maybe the 02:49:02.096 [EventThread] WARN o.o.b.a.c.SocketWrapper Could not perform sync for user[e9df6579-d1d9-4a8c-a24d-af93d0024e9a]: "400: Request contains an invalid argument." is causing the disconnect but in this case we need more logging to detect the invalid argument.
