To enable SSL trace in the SAP Cloud Connector perform following steps:

  • stop SAP Cloud Connector service
  • open <drive>:\sap\scc20\props.ini file with a text editor
  • add JVM parameter -Djavax.net.debug=ssl  to the end of #jvm section 
props.ini
#jvm

-Djavax.net.debug=ssl
  • start SAP Cloud Connector service
  • the SSL trace will be collected in <drive>:\sap\scc20\log\ljs_trace.log file
  • when SSL tracing is finished, stop SAP Cloud Connector service
  • remove the -Djavax.net.debug=ssl  JVM parameter from the props.ini file.

Ensure that JVM parameter is added to a new line otherwise, it has no effect on tracing like in this case:

props.ini
#jvm
...
-Djava.awt.headless=true 
-Dio.netty.recycler.maxCapacity.default=256-Djavax.net.debug=ssl


Since SAP Cloud Connector 2.12.2 the TLS trace can be enabled from the Cloud Connector UI:

It needs a cloud connector restart.
