Timeout when I try to use PROXY

[alexvrv]

Hi, I'm trying to use a proxy server but I only get "org.apache.http.conn.ConnectTimeoutException". This is the code I'm using. I've tried 3 methods for setting the PROXY server xD

String url = "https://forexe.mfinante.gov.ro/CABWeb/home";
            final WebClient webClient = new WebClient(BrowserVersion.CHROME, "x.xx.xxx.xxx", 8080);

//            ProxyConfig proxyConfig = new ProxyConfig("x.xx.xxx.xxx", 8080, "https");
//            webClient.getOptions().setProxyConfig(proxyConfig);

//            webClient.getOptions().getProxyConfig().setProxyHost("x.xx.xxx.xxx");
//            webClient.getOptions().getProxyConfig().setProxyPort(8080);
//            webClient.getOptions().getProxyConfig().setSocksProxy(false);

            webClient.getOptions().setSSLClientCertificateKeyStore(ks.getKeyStore(), null);
            webClient.getOptions().setSSLInsecureProtocol("TLS");
//            webClient.getOptions().setUseInsecureSSL(true);
            webClient.getCookieManager().setCookiesEnabled(true);
            webClient.setCssErrorHandler(new SilentCssErrorHandler());
            webClient.getOptions().setThrowExceptionOnScriptError(false);
            webClient.setIncorrectnessListener((message, origin) -> {});
            webClient.getOptions().setSSLContext(ks.getSSLContext(alias));

           HtmlPage htmlpage = webClient.getPage(url);

and this is the error

Am I missing something? ...

@alexvrv i use the final WebClient webClient = new WebClient(BrowserVersion.CHROME, "x.xx.xxx.xxx", 8080); approach from time to time to do some wire inspection using the Charles Web Proxy as local running proxy. Had no problems so far.

Does your proxy requires authentication?

[alexvrv]

No, it's without authentification. Just an IP and a PORT. JSOUP and HttpURLConnection works fine with just "System.setProperty("java.net.useSystemProxies", "true");". They take the Proxy settings from Windows.

[rbri]

Wild guess - does the proxy support http or only http/2?

[alexvrv]

Uff I really don't know xD but it works with every website (even old ones, government ones) so I guess it supports both.

[rbri]

maybe you can try to capture a wire log (see https://hc.apache.org/httpcomponents-client-5.4.x/logging.html)

Hopefully this might give a glue what is going on

[rbri]

@alexvrv any new ideas?
