Always getting timeout

[Gaurav Jha]

I am using async-http-client-2.0.37.jar in my java application. I am always getting Request timeout

java.util.concurrent.TimeoutException: Request timeout to www.google.co.in/172.217.26.163:80 after 60000 ms
    at org.asynchttpclient.netty.timeout.TimeoutTimerTask.expire(TimeoutTimerTask.java:43)
    at org.asynchttpclient.netty.timeout.RequestTimeoutTimerTask.run(RequestTimeoutTimerTask.java:48)
    at io.netty.util.HashedWheelTimer$HashedWheelTimeout.expire(HashedWheelTimer.java:663)
    at io.netty.util.HashedWheelTimer$HashedWheelBucket.expireTimeouts(HashedWheelTimer.java:738)
    at io.netty.util.HashedWheelTimer$Worker.run(HashedWheelTimer.java:466)
    at java.lang.Thread.run(Thread.java:748)

Please find my code which I am using below:

AsyncHttpClient asyncHttpClient = new DefaultAsyncHttpClient();
 asyncHttpClient.prepareGet("http://www.google.co.in/").execute(new AsyncCompletionHandler<Response>(){

                    public State onStatusReceived(final HttpResponseStatus status) throws Exception {
                        System.out.println(status.getStatusCode());
                        return State.CONTINUE;
                    }

                    @Override
                    public Response onCompleted(Response response) throws Exception{
                        System.out.println("completed : " + response.getStatusCode());
                        return response;
                    }

                    @Override
                    public void onThrowable(Throwable t){
                        t.printStackTrace();
                        System.out.println("throw");
                    }
                });

I am getting status code in the output as 200 but I am always getting the above timeout exception. I have tried different URLs as well, getting timeout for every URL. And one more issue is whenever I use https URL I don't even get status code, but it will timeout after 60s.

Please guide on what should I do to solve this.

Crystal ball says your organization requires you to set up a proxy to be able to reach internet.

Why do I need to setup a proxy to get this work, is it not possible to make HTTP requests without setting up proxy?
Will this also solve HTTPS issue?
If without proxy it won't connect to internet then how I was getting status codes?

No idea why you get timeouts.

What's for sure is that your code is broken: AsyncCompletionHandler is a concrete class, with some logic in "onStatusReceived" and you're breaking this logic as you override this method without calling super implementation.

OK sorry to bother you again, but I have also tried without onStatusReceived method as well but still getting timeouts. I am new to this so my questions might sound silly but please help me on this as I am stuck.

I used the below code without onStatusReceived

AsyncHttpClient asyncHttpClient = new DefaultAsyncHttpClient();

                asyncHttpClient.prepareGet("http://www.google.co.in").execute(new AsyncCompletionHandler<Response>(){

                    @Override
                    public Response onCompleted(Response response) throws Exception{
                        System.out.println("completed : " + response.getStatusCode());
                        return response;
                    }

                    @Override
                    public void onThrowable(Throwable t){
                        t.printStackTrace();
                        System.out.println("throw");
                    }
                });

Till now I haven't tried by setting up a proxy I will give that also a try. Any help is appreciated.

I tried by setting up the proxy and still am getting timeouts. Not sure what is causing this.

I used the example present in AsyncHttpClient repo (https://github.com/AsyncHttpClient/async-http-client/blob/master/example/src/main/java/org/asynchttpclient/example/completable/CompletableFutures.java) But I am still getting the following error :

Please guide what to do or what could be going wrong here.
