Introduction
Microsoft have included support for TLS 1.2 in their SQL Server drivers’ updates — https://blogs.msdn.microsoft.com/sqlnativeclient/2018/03/30/released-microsoft-ole-db-driver-for-sql-server/. TLS 1.2 support was not available in BPA Platform 2018 or any previous versions for any SQL Server connection or Microsoft SQL Server Trigger Agent connection.
Resolution
The SQL Server connection procedures for the store and the Microsoft SQL Server Trigger Agent have been amended to include support for TLS 1.2.
If you are using TaskCentre or BPA Platform and you have changed your SQL Server installation to use TLS 1.2, you must apply this hotfix.
