SocketTimeoutException由RxJava未处理

我有一个使用sdk版本25开发的Android项目 . 我使用RXJava作为我的线程管理和Retrofit库来打网络 .

我还实现了自定义拦截器来添加覆盖有趣的拦截（链：Interceptor.Chain）：响应？ {

val request = addHeader(chain)

    val response = chain.proceed(request)
    checkErrorResponse(response)

    return response

api调用将始终在RX Java流程中，我正在确定它 . 将我的APK放到Playstore后，Crashlytics会检测到崩溃 .

当我调查stacktrace时，我发现我的代码正好在我的自定义拦截器上 . 据我所知，崩溃是由 SocketTimeoutException 引起的，然后是一个超时请求 . 然后我尝试重现超时但无法完成 . 在我的环境中，异常总是由RX Java捕获并发送到onError（）方法 .

RX Java怎么没有 grab 崩溃？为了安全起见，我应该用catch块包装 proceed() 方法吗？
