What does error code 3003 mean?

Below are the common errors our users may encounter, and possible solutions.  

-3003 

This error happens when the mobile app can not establish a connection to the camera within a pre-defined time (the 30s).  

This is usually caused by network glitches. It may be resolved by re-try.  

Sometimes, there are reports, that the camera can be connected when the camera and the mobile phone are in the same Wi-Fi network. Once the mobile phone moves to another network (for example, 4G mobile internet, or work Wi-Fi), the camera can no longer be connected.  

When this happens, usually it means, the camera can reach our server, but the router the camera connected to rejects packets sent by our server to the camera. Double-check your router, to make sure it does not block UDP packets.
