The UID status on the IP camera’s user interface should be “Connected” otherwise, we won’t be able to view the camera through EnViewer.
Possible reasons why UID would be “Disconnected”:
- IP camera is not connected to the router and the internet. Verify connections.
- IP camera is behind 2 NAT (Router behind router). Make sure the IP camera is behind the first router. Better if there is just one NAT.
- The router does not support UPNP Forwarding. Verify it from manufacturer.
- The router supports UPNP Forwarding but it is not enabled
