as can see in above code have handled youtube service throws exception because receives null value when host on server or iis on company network.but when run code locally(development machine) doesn't throw exception. have spent days solving issue no avail.any appreciated. exception message server error in '/' application. value cannot null. parameter name: youtubeservice description: unhandled exception occurred during execution of current web request. please review stack trace more information error , originated in code.

exception details: system.argumentnullexception: value cannot null. parameter name: youtubeservice
