   Open Windows Task Manager and check whether the YDService.exe process exists.
   
2. If the agent process do not exist, possible reasons include the following:
   • The CWP agent is not installed on or has been uninstalled from the server. Please see Getting Started and follow the instructions to install the agent.
   • The agent has a conflict or crash and thus cannot be started.
3. Troubleshooting methods:
   • View the agent log stored in C:\Program Files\QCloud\YunJing\log.
   • Run the following command to manually start the agent: sc start ydservice.

Network Failures

If the process exists, but CWP is offline, the issue is caused by network disconnection in most cases. Please check the following:

1. Check whether the DNS has been modified. If any of the following commands returns a normal result, the DNS is correct:
   • Download address for the basic network (non-VPC servers): telnet s.yd.qcloud.com 5574.
   • Download address for VPC and CPM: telnet s.yd.tencentyun.com 5574.
2. Make sure the following ports are open: 5574, 8080, 80, and 9080.
