Suddenly it is no longer possible to login to CA PIM 12.X web interface.
Tryint to connect to https://<entm_server>:18443/iam7ac returns with a page not found, and trying to access https://<entm_server>:184437idmmanage returns a null error and no information about ac_env or ac_dir
Server.log is full of errors like the following
2021-07-09 13:10:47,775 DEBUG [org.jboss.mq.pm.jdbc2.MSSQLPersistenceManager] Connection attempt # 3 failed with SQLException
org.jboss.util.NestedSQLException: Could not create connection; - nested throwable: (com.microsoft.sqlserver.jdbc.SQLServerException: The driver could not establish a secure connection to SQL Server by using Secure Sockets Layer (SSL) encryption.

and of course nothing is loaded in server.log following these messages
Release : 12.8
Component : CA ControlMinder - Unix
This may occur if the security settings at the SQL sever acting as RDBMS have been changed to exclude TLS v 1.1, which is a common practice.
See for instance:
https://docs.microsoft.com/en-us/troubleshoot/windows-server/identity/disable-tls-1-1dot1-mbam-servers
This change will take effect when the RDBMS server is restarted
JBOSS requires TLS 1.1 for operation, unless it has been modified to use the more secure protocols
Revert back the TLS change at the SQL RDBMS server and reboot jboss
