Possible Cause:

1. In case of the layer 2 exchanger, the address is wrongly written.

2. In case of layer 3 exchanger, the port and physical address binding is done or not.

3. When arranging the firewall rules, whether the server is considered.

  Solution:

  Before searching the network fault, please be sure to use the ping command in the command mode to connect the address of the other party. Viewing the message returned after ping is a very important ring. If no message is returned, it indicates that some faults exist in the network.

  If the IP address and Mac address are bind, adding a new binding of IP address and Mac address of the video server within the exchanger is required.

  If the server has not been considered when exchanger arranging the firewall rules, it¡¯s necessary to allow the communication on 3000, 3001, 3002, 3003 and 80 ports for the server.
