This will be resolved fully via defect DE442855. The fix from that defect will update the automated HTTPS SSL configuration tools to use the stronger SHA-2 algorithm. The release that fix will be included in is yet to be determined.
To resolve this without waiting for the new automated tools, the following steps can be taken.
Another option would be to replace the existing Certificates with Certificate Authority (CA) signed SSL certificates that include a root and intermediate certificate for improved security.
