OKHTTP3 throws ConnectionShutdownException

Question

I am using okhttp3 to send an image to the server, this way:

final OkHttpClient cliente=new OkHttpClient();

    HttpUrl.Builder urlBuilder = HttpUrl.parse(getString(R.string.sendimageurl)).newBuilder();

    String url = urlBuilder.build().toString();
    Request request=new Request.Builder()
            .addHeader("imagebase64", toBASE64(bitmap))
            .addHeader("token", almacen.getToken())
            .url(url)
            .build();

(Yes, params are sent in the headers, don't blame me, its the way the service is built).

It is always entering in onFailure() method, launching ConnectionShutdownException:

I am not setting any interceptor in my call.

What can I do to send my image?

Thank you.

EDIT:

After Christopher's suggestion, I do:

final OkHttpClient cliente=new OkHttpClient();

    OkHttpClient client1 = cliente.newBuilder()
            .readTimeout(10000, TimeUnit.MILLISECONDS)
            .build();

    HttpUrl.Builder urlBuilder = HttpUrl.parse(getString(R.string.sendimageurl)).newBuilder();

    String url = urlBuilder.build().toString();
    Request request=new Request.Builder()
            .addHeader("imagebase64", toBASE64(bitmap))
            .addHeader("token", almacen.getToken())
            .url(url)
            .build();
    client1.newCall(request).enqueue(new Callback() {
       //stuff
     }

But no result, same exception.

EDIT 2:

After sea cat answer, I realized it should be a POST request. Changed to:

final OkHttpClient cliente=new OkHttpClient();

    HttpUrl.Builder urlBuilder = HttpUrl.parse(getString(R.string.sendimageurl)).newBuilder();

    String url = urlBuilder.build().toString();
    RequestBody requestBody = new MultipartBody.Builder()
            .setType(MultipartBody.FORM)
            .addFormDataPart("imagebase64", toBASE64(bitmap))
            .addFormDataPart("token", almacen.getToken())
            .build();

    Request request=new Request.Builder()
            .addHeader("imagebase64", toBASE64(bitmap))
            .addHeader("token", almacen.getToken())
            .url(url)
            .post(requestBody)
            .build();

(The data has to be sent in headers, but the post needs addFormDataPart, so I added them there too) but the exception is the same.

How big are your images? Maybe you can extend the connection timeouts within OkHttpClient — Christopher, Jan 29 '19 at 10:57
Is not really that big, in fact I am sending a thumbnail...How can I extend the timeout? — Fustigador, Jan 29 '19 at 11:00

Your request is of type get(). Is that what you want?

Thanks for pointing that out, actually it shold be a POST request. But it didn't solved the issue. But thanks, since that should be addressed too. – Fustigador Jan 29 '19 at 11:32
Tried to send the image without the data in headers...and despite that they told me that the data must be sent in headers, now it returns a 200. So I guess someone lied me, unadvertedly. I am upvoting you, since you put me in the right track. Thanks again! – Fustigador Jan 29 '19 at 11:43
Cheers, that put me in the 50s and I can comment now. I would suggest using Fiddler to see the traffic, you can see exactly what you send to the server, headers and all (android under 7 I think), and what the server comes back with. And play around with sending no payload to the server, I'm suspecting it'll just answer with a 200, but there might be a message with it – sea cat Jan 30 '19 at 11:38
