NVR Network Access - Connection Refused

NVR Network Access - Connection Refused


 


If you are not experiencing this issue:



If you are not currently experiencing this issue, we suggest hardening your local area network cyber security practices, especially via disabling port mapping / UPNP and port forwarding on your router, before it happens to you.

You can do so here in the NVR interface, but you also need to turn off port mapping / UPNP and port forwarding on your router.

If you are experiencing this issue:

 

Gathering information is going to be critical in order to prevent it from occurring again. As far as we can tell, the clients being attacked are being attacked repeatedly.

If possible, prior to rebooting the NVR and while the issue is actively occurring, pulling diagnostic information from the local display using a USB flash drive.


1. Navigate to Maintain - Backup - Diagnostic Info (At the top) and select the latest NVR diagnostic file and hit export at the bottom left.

 2. Navigate to Maintain - Network Info - Net Detect and perform a packet capture with the following parameters

Device Name:  This will be your USB flash drive
Select Port:  554
Select IP:  All


Then select the export button near the NIC connected to your LAN - while performing this task please try to access the local IP of the NVR via a computer, refreshing 3-4 times.  


Please repeat the packet capture process again after port 80.
