1. Enable TLS debugging in the server to troubleshoot SSL communication issues:
    $ dsconfig create-debug-target \
      --publisher-name "File-Based Debug Logger" \
      --target-name
    com.unboundid.directory.server.extensions.TLSConnectionSecurityProvider \
      --set debug-level:verbose \
      --set include-throwable-cause:true
    $ dsconfig set-log-publisher-prop \
      --publisher-name "File-Based Debug Logger" \
      --set enabled:true \
      --set default-debug-level:disabled
  2. Make the option take effect on a scheduled server restart.
    1. In the java.properties file, add -Djavax.net.debug=ssl to the start-ds line.
    2. To make the option take effect on a scheduled server restart, run bin/dsjavaproperties.
