SSLHandshakeException при попытке использовать веб-службу REST

Я пытаюсь использовать защищенную конечную точку отдыха через код Java следующим образом

public static void main(String[] args) {
    getUrl();
}

private static void getUrl(){
    System.setProperty("javax.net.ssl.keyStore", "C:\\Program Files\\Java\\jdk1.8.0_191\\keystore\\test.jks");
    System.setProperty("javax.net.ssl.keyStoreType", "JKS");
    System.setProperty("javax.net.ssl.keyStorePassword", "test123");    

    RestTemplate restTemplate = new RestTemplate();
    ResponseEntity<SignedURL> signedURLEntity = restTemplate.getForEntity("https://tfgts.xyz.com:16610/file-transfer/get-url?fmt=json", SignedURL.class);
    System.out.println("PUT URL : "+signedURLEntity.getBody().getPuturl());
}

Я импортировал сертификат test.jks следующим образом.

keytool -importkeystore -srckeystore .\test.jks -destkeystore %JAVA_HOME%/jre/lib/security/cacerts

Я смог найти псевдоним сертификата, который я импортировал, когда я выполнил команду ниже

keytool -list -keystore cacerts

Я использую eclipse IDE для запуска этого класса Java и настроил путь сборки Java проекта на путь JDK, куда импортируется сертификат. Кроме того, я приказал, чтобы JAVA_HOME в переменных среды пути был сверху.

Но все же я получаю следующую ошибку
