The VANWEBUI started task receives the following error after the upgrade.
java.lang.IllegalArgumentException: R_datalib (IRRSDL00) error: profile for ring not found (8, 8, 84)
Update the server.xml file Connector element keystoreFile value with the correct key ring name.
keystoreFile="safkeyringjce://KEY_RING_OWNER/KEY_RING_NAME"
Another possible resolution (but assuming all prior definitions are correct) is to clear the browser cache.
Refer to the Vantage tech doc Enable HTTPS with Certificates Stored in SAF Keyring section for more details.
