Hi Yun,

Please check if the license manager is up and running on your server and showing the licenses available for checkout. 
>>Ansys license management center (overview) – Ansys Optics (using the web interface/GUI)
>>How to check license status and availability – Ansys Optics (from the command prompt) 

Also, send the screenshot of your license configuration on your cluster.
