Пытаюсь сделать Https запрос из кода Java. Получаю следующий эксепшен:

При этом та же страница нормально открывается через Яндекс Браузер или браузер Хромиум-Гост.

В чём может быть проблема?
Вот мой код, из которого идёт вызов:

Security.setProperty("ssl.SocketFactory.provider", "ru.CryptoPro.ssl.SSLSocketFactoryImpl");

//SSL Контекст
SSLContext sc = getSSLContext(kmf,tmf,cipherSuites2.split(","),contextName);
sc.init(kmf.getKeyManagers(), tmf.getTrustManagers(), SecureRandom.getInstance("CPRandom", "JCP"));
HostnameVerifier hostnameVerifier = NoopHostnameVerifier.INSTANCE;
HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
HttpsURLConnection.setDefaultHostnameVerifier(hostnameVerifier);
URL url = new URL(baseUri + uri);
try {
HttpsURLConnection con = (HttpsURLConnection) url.openConnection();
con.setRequestMethod("GET");
con.setConnectTimeout(10000);
CookieHandler.setDefault(new CookieManager());
con.connect();
System.out.println("Connected: " + con);
} catch (Exception ex) {
ex.printStackTrace();
throw new Exception("Ошибка соединения",ex);
}
Заранее спасибо
