sql error on chart_needdatasource

[Priti]

I have created a reports library and using it to display multiple charts in reportbook in a project.
It runs fine on my local pc but gives error when put live.
the error it gives -

An error has occurred while processing Chart 'Chart1': A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

can u suggest where the issue can be?
i've checked the connection string and it is fine.

Hello Priti,

This is generic SQL error and not an error that is thrown from the reporting product. Verify the name and credentials of the connection string are correct. The connection you've used when creating and binding the reports, should be available in your application configuration file (web.config in case it is a web application/site).

Kind regards,
