Tower Enterprise relies on Java 11 (Amazon Corretto), which does not default to TLS v1.2.This may lead to some issues with 3rd party integrations that enforce TLS v1.2 (such as Azure Active Directory OIDC). Such problems can be addressed using the environment variables for the JDK, by explicitly setting TLS v1.2 as the default version:
_JAVA_OPTIONS="-Dmail.smtp.ssl.protocols=TLSv1.2
