Release : 4.9.1
Component : Web Portal - Data Masking
JRE version is updated to 1.8.292 in latest TDM portal. This JRE does not allow SSL handshake with TLS1.0 protocol. Since your database is expecting TLS1.0 communication, you are getting an error.
Upgrade the repository database to the version that supports TLS1.2 communication. Since the upgrade takes time, we downgraded jre version to 1.8.212 by replacing the jre folder from installation directory.
