During an upgrade, DTP retains the existing truststore found at <DTP_INSTALL>/jre/lib/security/cacerts. Because of this, if you have upgraded DTP multiple times, it's possible your truststore might not contain newly trusted certificate authorities. If your 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 <DTP_INSTALL>/jre/lib/security/cacerts. |
