What happened when the request for the qingguo camera server failed?

network problem, router setting problem, IP address conflict.

1. Network problem: First, check whether the network connected to the camera is normal. Make sure that the connection between the camera and the router is stable, and that the LAN where the camera is located has an available network connection.

2. Router settings: Sometimes, the settings of the network router may prevent the camera from connecting. Please check the settings of the router to make sure that it allows the camera to access the Internet and that no restrictions or shielding rules are enabled.

3. IP address conflict: if the IP address of the camera conflicts with other devices, it may lead to the inability to connect. Try to assign an independent IP address to the camera to ensure that it does not duplicate other devices.
