Error : The request failed with HTTP status 404: Not Found. when open sql report

Question

when i open my report built in sql from my application i get the error. The request failed with HTTP status 404: Not Found.

Answer 1

Do you have reporting services set up with the correct website and directory, and are you looking at that directory / website ?

Answer 2

The 404 or Not Found error message is a HTTP standard response code indicating that the client was able to communicate with the server but the server could not find what was requested. 404 errors should not be confused with "server not found" or similar errors, in which a connection to the destination server could not be made at all. A 404 error indicates that the requested resource may be available in the future.

Which means client-server communication is fine. What is missing and should be checked is reporting service running? once you verified this, check the provided reporting services configuration of your application.
