Citrix xenapp is newly installed on the server, but an error occurred when installing and calling the application

The Citrix server is unable to process your request to start this publised application at this time.
Please try again later. If the problem persists, contact your administrator.

The re installed operating system and Citrix failed to solve the problem. At present, the temporary solution is to restart Citrix service

You need to check or restart the relevant Citrix service, Citrix independent management architecture service

It takes a long time to restart the service, and it can be used normally after restart
