apache HTTP client : HttpHostConnectException
Bonjour ,
Je développe une application cliente qui appelle une API web. Lors du déploiement de l'application , elle fonctionne très bien sur ma machine et d'autres machines mais en l’exécutant par hasard sur une nouvelle machine d'un client , il n'est plus capable d'appeler l'API et en consultant les logs j'ai eu cette exception :

Il est à noter que l’application marche parfaitement sur d'autres machines.J'ai consulté les forums et j'ai vu des réponses propos des proxys mais j'avais une réponse claire pour résoudre c probléme.
Aide SVP
Merci
