Issue with Deployment on cloud

Hi All, We are facing an issue with our custom database which have deployed on the mendix cloud. When we try to access the APP it gives below error. Please see the snapshot for the log as below .   We are using mssql server version 2012 standard. Mendix Studio Pro 8.4.2    From log i can see it shows the connector error. So do we need license for the Mendix as we are using the free version for creating the app which is connected to our local DB.
