Getting following error-SQL 2016 SSRS

An error has occurred during report processing. (rsProcessingAborted)
Cannot create a connection to data source 'Recon'. (rsErrorOpeningConnection)
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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
The network path was not found

stupid question: did you check you connection strings? are they valid?


The issue is fixed. Some how we need change the data source in two locations. Once I changed that all working fine.

Thank You.
