IFS Cloud 22R2 virus scanner pod fails to startup with "Connection Refused"

I’m assisting a customer on setting up a remote deployment of 22R2, and the ifs-virus-scanner pod fails to start up with “Connection Refused” error message
 

09:12:15.681 [executor-thread-0] ERROR com.ifsworld.fnd.ScannerReadiness - Error occurred!

java.net.ConnectException: Connection refused (Connection refused)

Comparing to an internal environment (also remote deployment), it looks like the pod is trying to connect to database.clamav.net when it got the “Connection Refused” error message.

Any thoughts on how to resolve the issue?

Thanks!
