JDBC SQL Server Driver Version for Appian cloud instance version 23.4

Thanks for providing this information.  I found that chart as well.  In the Overview section, it says, "This article details the minimum requirements your system must meet to run Appian."  I assumed this meant on on-prem install.  Is it safe to assume that the minimum requirements are identical to a cloud instance on 23.4?

We are trying to connect to SQL Server running on a VM in Azure.  The SQL Server version is 2012 and the OS is Server 2012 as well.  We have a VPN and connectivity has been confirmed.  We know this because we can connect to a different SQL Server VM in Azure that is running SQL 2016 and Server 2012.  We are using a Connected System object to make the connection using a JDBC SQL Server data source.

Unfortunately, we aren't receiving any error messages to solve the problem.  We've checked TLS versions, configurations, etc. and no luck.  Therefore, I wonder if the JDBC SQL Server version is incompatible with SQL Server 2012.  If the JDBC SQL Server version in the cloud is 8.x, it should work with SQL 2012; however, it would not work with SQL 2022 which is the latest version of SQL Server.  This seems odd to me that a cloud instance of Appian would not support the latest version of SQL Server.  On the other hand, if the driver version is 12.x, it would support SQL 2022, but not 2012.  This would explain the inability to connect to SQL 2012 instance.  See the chart for Microsoft below:

Therefore, how do we know what the version of JDBC SQL Server driver is deployed to a cloud instance of Appian 23.4?  Thanks!
