Selenium-ChromeDriver SSL error/handshake failed

Question

My script is throwing a ton of SSL errors as below:

[19852:2032:0912/202419:ERROR:ssl_client_socket_impl.cc(1141)] handshake failed;
 returned -1, SSL error code 1, net_error -100

[19852:2032:0912/202419:ERROR:ssl_client_socket_impl.cc(1141)] handshake failed;
 returned -1, SSL error code 1, net_error -100

Everything works normally but the errors keep looping and eventually block the script causing it all to come to a halt.

I have tried to suppress the errors as below...but to no effect:

path_to_chromedriver = 'C:/Path/to/Chromedriver'
options = webdriver.ChromeOptions()
options.add_argument('--ignore-certificate-errors')
options.add_argument('--ignore-ssl-errors')
browser = webdriver.Chrome(chrome_options=options, executable_path = path_to_chromedriver)

I am unsure if the error is in my code above if there is something I should add that isn't there, or whether these errors can actually be suppressed.

If it is helpful, this is an old piece of code that was working fine until a few days ago. The site in question added some ad network scripts which caused some SSL certificate issues.

Any help appreciated.

You can try using the TrustManager packages, here's a sample

    SSLContext sslContext;
    TrustManager[] tmTrustAllCerts = new TrustManager[]{
            new X509TrustManager() {
                public java.security.cert.X509Certificate[] getAcceptedIssuers()
                {
                    return null;
                }
                public void checkClientTrusted(java.security.cert.X509Certificate[] certs, String authType) {}
                public void checkServerTrusted(java.security.cert.X509Certificate[] certs, String authType) {}
            }
    };

    try {
        sslContext = SSLContext.getInstance("SSL");
        sslContext.init(null, tmTrustAllCerts, new SecureRandom());
        HttpsURLConnection.setDefaultSSLSocketFactory(sslContext.getSocketFactory());
    }
    catch(Exception e) {
        System.out.println(e.getStackTrace());
    }

This is due to the unsafe address error. You can ignore this by adding parameters of "--ignore-certificate-errors".

Take the case in robot framework-selenium as example:

Open Browser http://127.0.0.1/8000 Chrome executable_path=C:/path/to/chromedrive options=add_argument("--ignore-certificate-errors")

This will solve the problem you got. If you ignore this argument, there is an error of chance got a "ERROR:ssl_client_socket_impl.cc".
