The same troubles occurred once more this morning around 05hUTC due to the camera "SNEB_FrontRight" - ipcam37 even if the UPnP service was disable on all IP cameras last week.
There is a camera spare available in the CEB-LAPP-office to replace with the faulty one . It will helpful if the swap could be done soon .
As consequence all the ITF Ethernet devices have to be reconnected to the network.
