Hello Microsoft Community ,
I have an issue that i can't identify it from where it's happening , so let me introduce the issue in bullet points format :
Am deploying a .NET Framework application , separated into frontend and backend part into iis in a windows 2012 server .
The frontend part is communicating with backend via API's ; ( the frontend part is built using eviromnement to refer the backend like http://myapp.domain.com/api ... ) , so everything was running smoothly
I tried to migrate to HTTPS for the endpoints ; so i made a new frontend build ( Angular ) that points to https://myapp.domain.com/api ... of course with making successefully an SSL certificate to establish communication .
The app is working smoothly , but suddenly , i see hangs , and exactly from from worker processes , and for the appropriate app pool for backend part , i see the accumlation of request and not connecting anymore , i can't get any response from the deployed backend any more , even seperately when using POSTMAN !
The app can get back working only if i restart the server , note that The CPU is not full , and memory also ; so threads of the app can find place to continue and have place to be executed.
Am using iis 8 and windows server 2012 R2 , and i would be so gratefull , if i get clear explanation about the root cause , contributing to the hangs and stopping backend.
