Troubleshooting Client Process Startup Issues

Check whether the CWP process is running.
Open the Windows Task Manager and check whether a process named YDService.exe is running.

  1. If the process is not found, the following possible causes are included:
    • The CWP is not installed, or the client has been uninstalled. In this case, see Quick Start to reinstall the client.
    • The client may have encountered an abnormal conflict or crash, preventing the process from starting.
  2. Troubleshooting methods:
    • Check the client logs, which are stored at C:\Program Files\QCloud\YunJing\log.
    • You can execute the following command to manually start the client: sc start ydservice.

Troubleshooting Network Issues

If the process exists but the CWP Client is offline, it is probably because the network is unavailable. Follow the steps below to troubleshoot:

  1. Check whether the DNS has been modified by executing the following command lines. If any one of them returns a normal result, it indicates that DNS functions properly.
    • For servers on the basic network (non-VPC servers), execute telnet s.yd.convergecloud.com 5574.
    • For VPC and CBM servers, execute telnet s.yd.convergecloud.com 5574.
  2. Firewall policy restrictions: Ensure that the following ports are open: 5574, 8080, 80, and 9080.
  3. If the CWP process is running and the client is offline for reasons other than network issues, please package the client logs that are located at C:\Program Files\QCloud\YunJing\log and contact a technical support engineer for assistance.
