I am trying to get SQL Server Management Studio (SSMS) table information using the database connector. When I run the microflow I created, I get the following error. The MendixPro console lists the error as such. Message An error occurred while processing your request.

The stacktrace should point you in the right direction: please doublecheck your connection settings.
“The TCP/IP connection to the host localhost, port 1433 has failed. Error: "connect timed out. Verify the connection properties. Make sure that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port. Make sure that TCP connections to the port are not blocked by a firewall.".”
