Initialization of Chest files FAILS

I installed Server 4.8 on my VPS web server - everything is OK but can’t Initialize/update the Chest Files
Get:
[i]
Initialization of Chest files

Program will try to load all Chest files from the following server: (null)

Action was completed with errors![/i]

I checked and the RPC is running. I ran a scan but the “Virus Recovery Database (VRDB): Not Done Yet”

What can I try to fix this?
Was the scan OK?
What does it mean when It’s unable to scan a file? Does that mean that file is compromised by malware in some way?
