Accessing Azure Synapse

So we are transitioning from Azure Sql DB to Azure Synapse Sql Pools. I figured this was a simple redirection of login since that’s all it took when connecting via mssql server, but Airflow keeps throwing this error:
(40532, b’Cannot open server “1433” requested by the login. The login failed.
I have reentered the credentials and tested the credentials in mssql server so I’m pretty sure its not a username/password issue, and the connection string Synapse shows 1433 is the correct port. Anyone have any advice on what might be happening? We use the generic MssqlOperator and Mssqlhook.
