Is there a problem in the communication network?

Solution: you can test the IP address of the PING remote device or the domain name address, and determine the network status through the PING message. If the state of the network is not good, it may be a problem of network routing problem or network blockage of the router. You can try to restart the remote router and the encoder device to re dial the connection and access. If the network communication is normal, but the video can not be accessed at this time, it is suggested that the front end router should be replaced to try to solve it.
