I am experiencing connectivity issue with Azure Function app attempting to connect to a SQL Managed Instance, both resource being configured on same Vnet.
- Azure Function cannot establish connection to SQL Managed Instance
- Connection Attempts are failing.

The error message suggests that you are using a client API for SAP Sybase Adapative Server, which is a different product from SQL Server and Azure SQL Managed Instance.
