Unable to scan workstations using agent anymore

Unable to scan workstations using agent anymore

Hi

I can no longer scan any Windows 8.1 machines using the agent.

I can still scan Windows 10 (with agent) and servers (without agent)

The server log file reports

 Problem while analysing exception caused during workstation scan.|org.xml.sax.SAXParseException; Premature end of file.
                   at org.apache.xerces.parsers.DOMParser.parse(Unknown Source)
                   at org.apache.xerces.jaxp.DocumentBuilderImpl.parse(Unknown Source)

I have tried updating ManageEngine Service Desk and rebooting server but no change.

Any ideas?
