Troubleshooting problems related to enforcement of HTTPS with TLS 1.2
Starting from application update 9.2.26, License Metric Tool enforces the use of HTTPS with TLS 1.2. See how to troubleshoot problems that you might encounter after the upgrade.
- The License Metric Tool user interface cannot be accessed
- If you bookmarked the URL to the License Metric Tool user
interface and the URL starts with

- The License Metric Tool server cannot connect to the MS SQL Server database
- The License Metric Tool server cannot connect to the MS
SQL Server database and the following error is returned in the tema.log file.
I SRVE0292I: Servlet Message - [tema]:.[ERROR] Cannot connect to the database: Java::ComMicrosoftSqlserverJdbc::SQLServerException: The driver could not establish a secure connection to SQL Server by using Secure Sockets Layer (SSL) encryption. Error: "The server selected protocol version TLS10 is not accepted by client preferences [TLS12]".
The problem occurs because secure communication with TLS 1.0 is enforced by MS SQL Server while License Metric Tool requires the use of TLS 1.2. Enable TLS 1.2 on MS SQL Server. For more information, see: KB3135244 - TLS 1.2 support for MS SQL Server.
