Cause:
There is no Workspace.xml file under the ConfigureFiles directory in the controller ftp; the data is incorrect.
Troubleshooting:
Check whether the data in Workspace.xml under ftp://192.168.39.220/ConfigureFiles/ contains anything unreasonable.
Solution:
Contact after-sales personnel, copy Workspace.xml from the controller's ftp, and send it to after-sales personnel.
Case sharing:
None.
