Unable to scan Linux clients: "Data storage error occurred while populating asset data"

Hello,

I have Desktop Central 10.0.310 free edition managing 25 computers (11 x Windows 10 Pro, rest Ubuntu 18.04LTS).

I can monitor the Windows computers fully, but I am unable to scan the Linux hosts: ""Data storage error occurred while populating asset data"

Ports on the servers are open, no firewall is on the clients: all machines are in an Active Directory domain; agents are installed, credentials are correct.

I have found this old post https://pitstop.manageengine.com/portal/community/topic/testing-desktop-central-agent-scanning-fails-error-data-storage-error-occurred-while-populating-asset-data-scanning-failed and I am wondering if this may be the issue?
