I am having an issue where  the  deploy template  has suddenly stopped working.  Any help with this issue would be appreciated.  I am running OME 2.3 and has been working fine until recently.  I have tried many reboots and have deleted and re-discovered devices.

Cannot get Service Tag and Node ID from device  for validation.
ERROR: Could not get the device's Service Tag and Node ID for verification 
File clean up failed : The system cannot find the file specified

> Template deployment failed.
A deployment job could not be created on the iDRAC.
- Template validation will be skipped
