Certificate Error when USM checks for updates

Hi,

I'm running USM V1.3.9.1.0231 on a Windows 10/64bit PC with Java 1.8.0_181-b13 and when I launch the USM I get the following error:

Certificate Warning

The system cannot be managed for the following reasons.

(X) Unable to validate the identity of the site {0} from the certificate.

(X) Certificate is improperly signed

System: colu.emc.com [EMC Corporation]

Issuer: Entrust Certification Authority - L1K ["Entrust, Inc."]

I can then click on Details, Reject or Help.

If I click on Reject I can still log on to our array and manage it but USM cannot connect to EMC to download updates.
