You should note that as of Retrofit2 all responses with code 2xx will be called from onNext() callback and the rest of HTTP codes like 4xx, 5xx will be called on the onError() callback, using Kotlin I've came up with something like this in the onError() :

mViewReference?.get()?.onMediaFetchFinished(downloadArg)
  if (it is HttpException) {
    val errorCode = it.code()
    mViewReference?.get()?.onMediaFetchFailed(downloadArg,when(errorCode){
      HttpURLConnection.HTTP_NOT_FOUND -> R.string.check_is_private
      else -> ErrorHandler.parseError(it)
    })
  } else {
    mViewReference?.get()?.onMediaFetchFailed(downloadArg, ErrorHandler.parseError(it))
  }
