Error description

  • IBM  Dependence Based Build - DBB v1.0.x
    The ClientHello that is sent from DBB may fail since it has
    TLSv1 for the protocol and some sites allow only TLSv1.2
    
    In the build log you may see these errors:
    Default Executor-thread-301, fatal error: 40: Client
    requested protocol TLSv1 not enabled or not supported
    
    CWWKO0801E: Unable to initialize SSL connection.
