1. Usually we will assist our customers to install the latest version of our fleet management platform of CMSV6. After install the server, we need to do the port forwarding of the below ports used by CMSV6 server; (after ports forwarding, you can check if the ports are open by telnet ip port)

6602-6612 tcp + udp

6613-6613 tcp

6617-6622 tcp

6630-6636 tcp

2121-2162 tcp

WEB port tcp

（WEB port default: 80/8080/88/8088 optional)

Usually if the ports are ok, the server should run properly. 

2. And if still have problem, you can check the server config as below:
