Response 404 - UPNNotFound
It may not really be caused by UPNNotFound, but most caused by StoreFront authentication for various reasons:
- Communication error between Session Remote Start and StoreFront
- Open Web.config, double confirm the ‘StoreFrontServer’ option. A recommended practice is to set ‘StoreFrontServer’ by copy from ‘Receiver from Web Sites’ in StoreFront UI. Please note that the StoreFront store name is case-sensitive.
- Try to open ‘StoreFrontServer’ by browser, check if there is a connection or certificate error. (Do not need to login, just check if the web page can be visited normally.)
- Open CDF trace tool or enable Session Remote Start log file, check if there is any error detail.
- StoreFront issue Open Event Viewer -> Applications and Services Logs -> Citrix Delivery Services to check StoreFront log
- FAS issue For step #2, the error may be related to FAS, please refer to the FAS section of the checklist above.
Request Timeout
- Session Remote Start has a ‘RequestTimeoutSeconds’ option in Web.config. When request duration reaches the timeout, Session Remote Start will respond with status code 408 and body content.
- Session Remote Start will never terminate http connection without response. Please check if there is any timeout related setting in the caller.
- For the ‘LaunchResource’ API, there is an optional parameter ‘WaitForLogonNotification’ recognized as true by default. For the VDAs really take a long time for launching, ‘WaitForLogonNotification’ can be set to false. API will respond immediately and execute the launching process in the backend.
