Retrofit "java.net.ProtocolException: Unexpected status line", Anyone?

My Android app crashed with the following stack trace, but when I try it from a desktop rest client it works well. Does anyone know what the problem might be?

You can fix this by setting the header value @Headers("Connection:close") on your retrofit method.
This worked for me.

i add a network interceptor and add the close connection header to it for the okhttp3 client.

okHttpClient = new OkHttpClient.Builder()
                .addNetworkInterceptor(new Interceptor() {
                    @Override
                    public Response intercept(Chain chain) throws IOException {
                        Request request = chain.request().newBuilder().addHeader("Connection", "close").build();
                        return chain.proceed(request);
                    }
                })
                .build();

And that solve the problem. Hope it helps!

Also getting this response error when sending two POST requests in quick succession. The solution is to add header "Connection: close" for both of these requests.

Something is causing problems with the response body length of the preceding HTTP request, and that's causing the pooled connection to become corrupted.

The preceding request was interpreted by OkHttp to have no body, but it has this body:

{"Data":[],"CustomStatusCode":200,"Status":"success"}

It's probably either a bug in the server, or a bug in OkHttp, depending on which headers and code was sent by the preceding URL. If you can paste the request that precedes this failure, we can figure out whose fault it is!
