Я использую HtmlUnit для получения некоторой информации с веб-сайта. Он работает, когда я не за прокси. При работе через прокси, я использую этот код, чтобы установить конфигурацию:HtmlUnit за прокси
WebClient webClient = new WebClient(BrowserVersion.FIREFOX_45);
ProxyConfig proxyConfig = new ProxyConfig();
proxyConfig.setProxyAutoConfigUrl(proxyAutoConfigUrl);
webClient.getOptions().setProxyConfig(proxyConfig);
HtmlPage page = webClient.getPage(config.read().getString("homepage.url"));
FrameWindow fw = page.getFrameByName("mainDataIframe");
...
Но я всегда получаю сообщение об ошибке:

ERROR AWT-EventQueue-0 PageReader - com.gargoylesoftware.htmlunit.ElementNotFoundException: elementName=[frame or iframe] attributeName=[name] attributeValue=[mainDataIframe]
Эта ошибка никогда не происходит без прокси или в браузере. Есть ли кто-то с идеей, почему эта ошибка происходит? Или, может быть, кто-то, кто знает, как найти различия при работе за прокси?
