Databricks connect with Azure SQL Database

While following a Data Engineering hands-on tutorial on a YouTube channel, I ran into a JDBC connection failure in a Medallion architecture (Bronze to Silver pipeline).

Interestingly, my initial connection configuration code runs successfully, but the actual read operation using spark.read.jdbc throws an error. Both connections use the same personal account login.

Error: [FAILED_JDBC.CONNECTION] Failed JDBC jdbc:sqlserver:*********(redacted) on the operation: SQLSTATE: HV000

Why is spark.read.jdbc throwing a [FAILED_JDBC.CONNECTION] error with SQLSTATE: HV000 when the basic connection details are correct and working elsewhere? Any help to resolve this is greatly appreciated.
