3. Update the console configuration file:
   1. Find ssl configuration element in $BIGINSIGHTS_HOME/console/wlp/usr/servers/waslp-server/server.xml.
   2. Add attribute** sslProtocol=“TLS”**.
   For example: <ssl clientAuthenticationSupported=“true” id=“defaultSSLSettings” keyStoreRef=“defaultKeyStore” sslProtocol=“TLS”/>
4. Restart the console: $BIGINSIGHTS_HOME/bin/start.sh console
