iLO: The Remote Console is unavailable, it is already in use by a different client.

If you use the remote console in HP Remote Insight Lights-Out and gets the message “The Remote Console is unavailable, it is already in use by a different client.” you need to reset the iLO. The easiest way to reset iLO is to go to network settings and just hit apply. This will apply the current networking configuration (you haven’t done any changes) and the iLO will reset.
