Can't connect to data source through Test connection
Hello! I have the following situation with all of my reports on Report Server: 1) I go to Manage -> Data sources and click "Test connection". Then the following error occurs: "The error occurs. Please try again later" and no more detailed information on number of error or what I should check. 2) I check if the refresh of the report was succesful and I see that the refresh was sucessfully completed 30min ago: So I guess the connection to the data sources is fine. Could anybody please tell what could be the problem or where should I strart looking? Why "Test connection" doesn't work? Thank you!
