Connection Timed Out: Connect + TRTH Rest API Call

I am getting connection timeout when I try to run the DSS2SearchByRIC.java.
Is there a proxy setting that I need to change in my eclipse?

The postman GET request works just fine.

I got the same exception after adding a "https" parameter while creating HttpHost.

HttpHost proxy = new HttpHost(proxyHostName, proxyPortNumber, "https");

javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?

However, if I remove the "https" parameter, it works fine.

HttpHost proxy = new HttpHost(proxyHostName, proxyPortNumber);

Please try to set connection timeout in the code.

    private int timeout=30;
    private RequestConfig config = RequestConfig.custom()
    		  .setConnectTimeout( timeout * 1000)
    		  .setConnectionRequestTimeout(timeout * 1000)
    		  .setSocketTimeout(timeout * 1000).build();
    private CloseableHttpClient httpclient = HttpClientBuilder.create().setDefaultRequestConfig(config).disableContentCompression().build();

I found this code at http://www.baeldung.com/httpclient-timeout.

Thank you for the reply! I still get the same timeout error.

I get the following error:

javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?

Any idea why I get that?

Jirapongse

Are you using proxy?

This error was mentioned in stack overflow.

san tang

Yes. We have proxy and I have programmatically setup the system proxy.

@Jirapongsei

Do I need to setup something for the SSL?

Jirapongse

It may relate to the Proxy. Can you share the code? I will try it in my environment.

Please find below the sample code:
