Invalid Mashup Expression using supplied values. inner exception: Microsoft SQL: 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)
Hi @brian29black,
Any firewall changes recently?
If yes, then please make sure "sqlbrowser.exe and/or UDP port 1434 are under firewall exception."
Further , for more details about the connecting error, please check the blog first:
SQL NetWork Interfaces, error: 26 -Error Locating Server/Instance Specified
Please post back if issue insists.

Michael
