该异常通常在使用HTTPS进行网络请求时出现，解决方法是在网络请求之前设置SSLContext，为其配置信任的证书。具体代码示例如下：

try {
    SSLContext sslcontext = SSLContext.getInstance("TLS");
    sslcontext.init(null, new TrustManager[] { new X509TrustManager() {
        public void checkClientTrusted(X509Certificate[] chain, String authType) {}
        public void checkServerTrusted(X509Certificate[] chain, String authType) {}
        public X509Certificate[] getAcceptedIssuers() { return new X509Certificate[0]; }
    } }, new SecureRandom());
    HttpsURLConnection.setDefaultSSLSocketFactory(sslcontext.getSocketFactory());
    HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier() {
        @Override
        public boolean verify(String hostname, SSLSession session) {
            return true;
        }
    });
} catch (Exception e) {
    e.printStackTrace();
}
