I am using the Databricks JDBC driver (https://databricks.com/spark/jdbc-drivers-download) to connect to Azure Databricks through a VPN.

I am connecting through a SAAS low-code platform, Appian, so I don't have access to any more logs. We have set up and established a VPN connection from Appian to our Azure Databricks environment. We have also installed the Databricks JDBC Driver on this environment.

We have also configured a DNS in the Appian environment to resolve the azure databricks URL (painted out in screenshot below) to the private IP address within Azure Databricks.
