Forcing TLS 1.2
From Observer GigaFlow Support | VIAVI Solutions Inc.
You can force the JRE to only allow specific TLS versions. Edit the gigaflow start service file /etc/systemd/system/gigaflow.service Change the ExecStart line to include
-Dhttps.protocols=TLSv1.2 -Djdk.tls.client.protocols=TLSv1.2
An example of how it should now loog
ExecStart=/opt/java/bin/java -Xms364M -Xmx16000M -Dhttps.protocols=TLSv1.2 -Djdk.tls.client.protocols=TLSv1.2 -Djava.net.preferIPv4Stack=true -Djava.library.path=./dist/lib/ -Djava.awt.headless=true -XX:+CrashOnOutOfMemoryError -XX:+HeapDumpOnOutOfMemoryError -classpath ./dist/ROS.jar:./dist/lib/* ros.ROS
When done, reload the services file and then gigaflow service
systemctl daemon-reload systemctl restart gigaflow
