I am getting lot of Socket Read Timout when I try to read a response from my
post request. I am using OKHttpClient verion 3.11.0 with the following configuration:

@Bean

OkHttpClient okHttpClient() {

def loggingInterceptor = new HttpLoggingInterceptor()

loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY)

Dispatcher dispatcher = new Dispatcher()

dispatcher.setMaxRequests(200)

dispatcher.setMaxRequestsPerHost(200)



return new OkHttpClient()

        .newBuilder()

        .eventListenerFactory(PrintingEventListener.FACTORY)

        .retryOnConnectionFailure(true)

        .connectTimeout(30000, TimeUnit.MILLISECONDS)

        .readTimeout(30000, TimeUnit.MILLISECONDS)

        .dispatcher(dispatcher)

        .connectionPool(new ConnectionPool(200, 30, TimeUnit.SECONDS))

        .addNetworkInterceptor(loggingInterceptor)

        .addInterceptor(loggingInterceptor).build()



}

The code to process the request and response is given below:

Response r = client.newCall(request).execute()

r.withCloseable { response ->

def returnable



if (response.header('Content-Type')?.contains('application/json')) {

    def body = response.body().string()

    if (body.trim().isEmpty()) {

        returnable = [:]

    } else {

        try {

            def result = new JsonSlurper().parseText(body)

            return result

        } catch (any) {

            log.error('Failed to parse json response: ' + body, any.message)

            throw any

        }

    }

} else if (response.header('Content-Type')?.contains('image/jpeg')) {

    returnable = response.body().bytes()

} else {

    returnable = response.body().string()

}

return returnable

}

I add event listener, I see that the httpclient call responseBodyStart event and it hangs there and when timeout seconds reached, the call failed and throw Socket Read timeout exception. Is there anything missing in my configuration?

Event listener shows
responseHeaderStart or responseBodyStart followed by connectionReleased after specified timeout(30s) reached?

Please find the event trace and exception trace below:
