This is an issue with unsupported TLSv1.0 which is still used by the script. We just need to specify the TLS version in the script to overcome this issue. Flexnet server after upgrade have stopped using TLSv1.0, v1.1. We need to make the following changes on the /opt/zrt/ script as below, so that we force zrt script to use TLS1.2

if which java >/dev/null; then
cd /opt/zrt && java -Dhttps.protocols=TLSv1.2 -jar /opt/zrt/ZimbraCMSClient.jar -p /opt/zrt/
if [ -z ${JAVA_HOME} ]
echo There was not a JAVA_HOME set. Please set a JAVA_HOME system variable.
cd /opt/zrt && ${JAVA_HOME}/bin/java -Dhttps.protocols=TLSv1.2 -jar /opt/zrt/ZimbraCMSClient.jar -p /opt/zrt/
