java.net.SocketTimeoutException: timeout

With OkHttp library, application is facing following SocketTimeoutException issue. If request size is less, then it is working fine(Less than 1MB). I am getting this exception within 10 seconds, even my socket timeout(readTimeout) value is much higher. It is consistently failing for a request(Size is 1.8MB). When I executed a request with HttpUrlConnection it is working fine. What could be a possible reason of failure?

For OkHttp 3 the default value for OkHttp is 10 seconds. You can increase the timeout to 30 seconds.

OkHttpClient client = new OkHttpClient();
client.setConnectTimeout(30, TimeUnit.SECONDS); // connect timeout
client.setReadTimeout(30, TimeUnit.SECONDS);    // socket timeout

I solved that problem increasing writeTimeout().

Try:

OkHttpClient.Builder builder = new OkHttpClient.Builder();
builder.connectTimeout(5, TimeUnit.MINUTES) // connect timeout
.writeTimeout(5, TimeUnit.MINUTES) // write timeout
.readTimeout(5, TimeUnit.MINUTES); // read timeout

okHttpClient = builder.build();

this resolved my problem:

OkHttpClient innerClient = new OkHttpClient.Builder()
            .connectTimeout(5, TimeUnit.MINUTES) // connect timeout
            .writeTimeout(5, TimeUnit.MINUTES) // write timeout
            .readTimeout(5, TimeUnit.MINUTES) // read timeout
            .build();

You need to understand that only adding this won't solve your problem:

OkHttpClient.Builder()
            .connectTimeout(10, TimeUnit.SECONDS)
            .readTimeout(10, TimeUnit.SECONDS)
            .writeTimeout(10, TimeUnit.SECONDS)

If you are using Kotlin + Retrofit + Coroutines then just use try and catch for network operations like,

viewModelScope.launch(Dispatchers.IO) {
        try {
            val userListResponseModel = apiEndPointsInterface.usersList()
            returnusersList(userListResponseModel)
        } catch (e: Exception) {
            e.printStackTrace()
        }
    }

Where, Exception is type of kotlin and not of java.lang

This will handle every exception like,

1. HttpException
2. SocketTimeoutException
3. FATAL EXCEPTION: DefaultDispatcher etc

Here is my usersList() function

@GET(AppConstants.APIEndPoints.HOME_CONTENT)
suspend fun usersList(): UserListResponseModel

Use this for Kotlin

 val client1 = OkHttpClient.Builder()
                .connectTimeout(2, TimeUnit.MINUTES)
                .writeTimeout(2, TimeUnit.MINUTES) // write timeout
                .readTimeout(2, TimeUnit.MINUTES) // read timeout
                .addInterceptor(
                    BasicAuthInterceptor(
                        AmvaccAppConstants.AUTHENTICATE_USER_NAME, AmvaccAppConstants.AUTHENTICATE_USER_PASSWORD
                    )
                )
                .addInterceptor(interceptor)
                .build()

If you are using Retrofit and Kotlin then use following code:
    var BASE_URL:String="Your URL"
    val clientSetup = OkHttpClient.Builder()
        .connectTimeout(1, TimeUnit.MINUTES)
        .writeTimeout(1, TimeUnit.MINUTES) // write timeout
        .readTimeout(1, TimeUnit.MINUTES) // read timeout
        .build()

    val getClientApi: ApiInterface
        get() {
            var retrofit: Retrofit =  Retrofit.Builder()
                .baseUrl(BASE_URL)
                .addConverterFactory(ScalarsConverterFactory.create())
                .addConverterFactory(GsonConverterFactory.create())
                .client(clientSetup)
                .build()
        }

Run into a Run Catching

runCatching {
       service
}
 .map {
       if (it.isSuccessful && it.body() != null) {
           Success(Unit)
       } else {
           Error(Failure.AuthError.error(it.errorBody()))
       }
}
 .getOrElse {
       Error(Failure.Throwable(it))
}

In my case adding ping interval to OkHttp helps a lot in reducing number of SocketTimeoutExceptions in the app.

OkHttpClient.Builder()
        .pingInterval(3, SECONDS)
        .build()

but i am not sure if these timeouts were related to request size. I mentioned it also in this issue on github reported to OkHttp library

Check if your url is correct. This error can be because of wrong url line
