I am trying to get an Input Stream from a website, but all I get is: "Trust anchor for certification path not found" [duplicate]

I am trying to send a web request to this websitein order to gather information about the status of a public service.

The SSL certificateof the website seems fine, I did run the command for checking the certificate and it seems to be working.

openssl s_client -connect www.trentinotrasporti.it:443

The output of the command is:

The website is working correctlyusing the Browser, the https works, but once I try to send a web request I get issues from the SSL certificate. Note that the website isn't mine.

To send the web request I call this function, and I use as parameter the URL of the website:

public static String SendWebRequest(String webUrl){    Log.i("NetworkUtils", "Sending web request to the server "+webUrl+"...");    HttpsURLConnection urlConnection = null;    try {        URL url = new URL(webUrl);        urlConnection = (HttpsURLConnection) url.openConnection();        urlConnection.setRequestMethod("GET");        urlConnection.setConnectTimeout(10000);        urlConnection.setReadTimeout(10000);        InputStream inputStream = new BufferedInputStream(urlConnection.getInputStream());        String formattedStream = FileUtils.ReadStream(inputStream);        inputStream.close();        return formattedStream;    } catch (Exception e) {        e.printStackTrace();    } finally    {        if (urlConnection != null)            urlConnection.disconnect();    }    return ErrorString;}

I wasn't able to figure out why I get this error everytime: "javax.net.ssl.SSLHandshakeException: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found." just after executing the web request.

I should mention it's just this website prompting the error, if I change URL it's working as it should, maybe there is a parameter required for connecting to the web server?

Here is the logcat showing the error:
