SSLHandshakeException - Chain chain validation failed, how to solve?

问题

in my application I am trying to do a HTTPS POST request to my server. However, I keep getting SSLHandshakeException - Chain chain validation failed, all the time. I tried to send a request using POSTMAN and I got a response from the server. What can be causing this error when I try to send the request from the application?

Here a code snippet where I try to send the post request:

   public static JSONObject getDataLibConfiguration(Context context) throws HttpRequestException {

    int statusCode = 0;

    JSONObject commonInformation;
    HttpsURLConnection connection = null;

    try {

        commonInformation = ConfigurationProcessor.getCommonInformation(context);
        if (commonInformation == null) {
            return null;
        }

        URL url = new URL(BuildConfig.SERVER_CONFIG_URL);
        if (BuildConfig.DEBUG) {
            LogUtils.d(TAG, "url = " + url.getPath());
        }

        connection = getHttpsConnection(url);
        connection.setDoOutput(true);
        connection.setDoInput(true);
        connection.setRequestMethod("POST");
        connection.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
        connection.setRequestProperty("Content-Encoding", "gzip");

        byte[] gzipped = HttpUtils.gzip(commonInformation.toString());
        cos = new CountingOutputStream(connection.getOutputStream()); //<-- This is where I get the exception
        cos.write(gzipped);
        cos.flush();

        statusCode = connection.getResponseCode();
        // More code her
 }

private static HttpsURLConnection getHttpsConnection(URL url) throws IOException, GeneralSecurityException {

        HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();

        try {
            SSLContext sslContext = SSLContext.getInstance("TLS");
            MatchDomainTrustManager myTrustManager = new MatchDomainTrustManager(url.getHost());
            TrustManager[] tms = new TrustManager[]{myTrustManager};
            sslContext.init(null, tms, null);
            SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();
            connection.setSSLSocketFactory(sslSocketFactory);
        } catch (AssertionError ex) {
            if (BuildConfig.DEBUG) {
                LogFileUtils.e(TAG, "Exception in getHttpsConnection: " + ex.getMessage());
            }
            LogUtils.e(TAG, "Exception: " + ex.toString());
        }
        return connection;
    }

回答1:

In my case it was wrong date on phone.

Fixing date resolved an issue

回答2:

The problem was that the certificate was expired.

public static void trustEveryone() {
        try {
            HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier(){
                public boolean verify(String hostname, SSLSession session) {
                    return true;
                }});
            SSLContext context = SSLContext.getInstance("TLS");
            context.init(null, new X509TrustManager[]{new X509TrustManager(){
                public void checkClientTrusted(X509Certificate[] chain,
                                               String authType) throws CertificateException {}
                public void checkServerTrusted(X509Certificate[] chain,
                                               String authType) throws CertificateException {}
                public X509Certificate[] getAcceptedIssuers() {
                    return new X509Certificate[0];
                }}}, new SecureRandom());
            HttpsURLConnection.setDefaultSSLSocketFactory(
                    context.getSocketFactory());
        } catch (Exception e) { // should never happen
            e.printStackTrace();
        }
    }

or check system date of your device - I had this Exception when I tried to connect with wrong date!..

回答4:

If anyone come across this issue pertaining to specific device, then the reason should be because of incorrect date set in the device.

回答5:

If you're using an emulated device it may solve the problem if you just 'Cold Boot' it.

Sometimes the date on those things can get stuck if you let them run for some time, which results in this expired-certificate-problem.

回答6:

I fixed it by just changing the api's base url from "https" to "http"
