Retrofit2 request gives SocketTimeoutException:

When I try request service to use Retrofit2 in android, server response gives below error, exception : connect timed outjava.net.SocketTimeoutException: connect timed out at why I got socketTimeout exception in send Request?

request service: http://182.20.1.14:2020/api/MainAppExternal/UpdateFcmId

private Retrofit retrofit(String url, boolean addLogInterceptor, int timeout) {
    return new Retrofit.Builder()
            .baseUrl(url).client(getOkHttpClient(addLogInterceptor, timeout))
            .addConverterFactory(GsonConverterFactory.create(LocalGsonBuilder.getInstance().getGson()))
            .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
            .build();
}

private OkHttpClient getOkHttpClient(boolean addLogInterceptor, int timeout) {
    OkHttpClient.Builder httpClient = new OkHttpClient.Builder()
            .connectTimeout(CONNECTION_TIMEOUT, TimeUnit.SECONDS);

    setupInterceptor(httpClient, addLogInterceptor);
    setupTimeout(httpClient, timeout);

    return httpClient.build();
}

private void setupInterceptor(OkHttpClient.Builder httpClient, boolean addLogInterceptor) {
    if (addLogInterceptor) {
        httpClient.addInterceptor(new ConnectionInterceptor());
    }

Add getOkHttpClient function like this.

private OkHttpClient getOkHttpClient(boolean addLogInterceptor, int timeout) {
    OkHttpClient httpClient = new OkHttpClient.Builder().
            connectTimeout(timeout, TimeUnit.SECONDS).readTimeout(timeout, TimeUnit.SECONDS).build();
    setupInterceptor(httpClient, addLogInterceptor);
    return httpClient.build();
}
