I created an excel service application and added in service connections proxy to the web application, but in app server where I enabled excel service application pool is stopped every time. when I open excel document in the browser it shows below error.
unable to process the request
when I check in event viewer I found below error
The application pool has been disabled. Windows Process Activation Service (WAS) did not create a worker process to serve the application pool because the application pool identity is invalid.
