We copied our SSRS reports from a 2012 server to a 2016 server. When I try to edit a report using VS 2017 and click on the dataset I get the following error regarding the sql data source. The reports run fine and the web application can access the sql server database just fine. Not sure where to look.
The network path was not found

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:
