This can be caused by problems with the certificates in the Tomcat keystore
Default location and filename: SymantecDLP\Protect\tomcat\conf\.keystore
Certificate has been revoked
In one case a production server certificate was imported into a test server keystore resulting in the test server keystore having two private/public key pairs.
Removing that certificate resolved the issue.
Use the keytool located in SymantecDLP\jre\bin to view the certificates in the keystore and check for valid information i.e. host names, CA Root and Intermediaries, etc.
This will list the certificates and their alias from the keystore.
keytool -list -v -keystore pathto\.keystore
You can remove a certificate with the keytool
keytool -delete -alias CertAlias -keystore .keystore
