During an upgrade, License Server DTP retains the existing truststore found at <LS<DTP_INSTALL>/app/jre/lib/security/cacerts . Because of this, if you have upgraded License Server DTP multiple times, it's possible your truststore might not contain newly trusted certificate authorities. If your License Server DTP requires connecting to an external server with a certificate signed by one of these newly trusted certificate authorities, you may need to manually update the truststore at <LS<DTP_INSTALL>/app/jre/lib/security/cacerts . |
