Cause: Outdated version of iDRAC firmware.
Checking the current iDRAC firmware version:
While logged into the iDRAC7 Web UI, click the About link to display the currently installed iDRAC firmware version.

Resolution: 

  • upgrade your idrac firmware  works for me

DRAC5 Home

iDRAC6 Home

iDRAC7 Home

iDRAC8 Home

iDRAC9 Home

most of the chance it will work fine. however, if it still fails after firmware update, therefor you need to clear java cache.

  • under programs (or control-panel) start “Configure-Java” or Java-Control-Panel
  • General -> Settings -> Delete files -> select all 3 checkboxes
