Je travaille actuellement sur le pilote cpp de Datastax en C et je travaillais sur quelques exemples lorsque je suis tombé sur un problème très trivial. En essayant d'exécuter la commande Authentification de base script ici, j'ai trouvé cette erreur qui s'affiche et l'exécution du code se bloque.
L'erreur :
1587040775.210 [ERROR] (cluster_connector.cpp:192:void datastax::internal::core::ClusterConnector::on_connect(datastax::internal::core::ControlConnector*)): Unable to establish a control connection to host 127.0.0.3 because of the following error: Underlying connection error: Connect error 'connection refused'

Quels peuvent être ces protocoles qui ne sont pas pris en charge par ma machine ? De plus, après le dernier avertissement, qui est le suivant trying protocol v4
il se coince. J'utilise Casssandra 3.10+, Cpp-driver 2.13.
Toute personne ayant une solution de contournement ou une solution serait d'une grande aide. Merci d'avance
