Android Connection refused on proxy using OkHttp3

Question

I'm getting Connection refused error when I'm using a proxy configuration in Android Studio and send a request to server.

Does anyone have a light about this?

This is my Client builder:

 SSLContext sslContext = SSLContext.getInstance("SSL");
 TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
 trustManagerFactory.init(keyStore);
 KeyManagerFactory keyManagerFactory = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
 keyManagerFactory.init(keyStore, keyStorePass.toCharArray());
 sslContext.init(keyManagerFactory.getKeyManagers(), trustManagerFactory.getTrustManagers(), new SecureRandom());

 client = new OkHttpClient.Builder().sslSocketFactory(sslContext.getSocketFactory())
         .hostnameVerifier(new HostnameVerifier() {
             @Override
             public boolean verify(String s, SSLSession sslSession) {
                 return true;
             }
         }).connectTimeout(timeout, TimeUnit.MILLISECONDS)
         .readTimeout(timeout, TimeUnit.MILLISECONDS)
         .writeTimeout(timeout, TimeUnit.MILLISECONDS).build();

This is the Error log:

Does this answer your question? [OkHTTPClient Proxy authentication how to?](https://stackoverflow.com/questions/35554380/okhttpclient-proxy-authentication-how-to) — K_mns, Nov 09 '20 at 00:05
No this doesnt answer my question. I edited with the error log — Victor Soares, Nov 09 '20 at 00:49
causedby : connect failed: ECONNREFUSED (Connection refused) it means nothing is listening to IP nor Port, first disable firewall and try also check your ip address via ipconfig/all, let me know if it worked or not ! — K_mns, Nov 09 '20 at 01:16
There is nothing wrong with the IP or firewall as the problem only occurs when the proxy is configured. The connection works if I access without the proxy — Victor Soares, Nov 09 '20 at 13:03
