Chrome停止请求15秒

我们有一个角度2应用程序随机停止请求15秒 . 问题似乎是铬/ IP连接耗尽了铬 . 问题只出在chrome中 . 请求dosent在chrome dev选项卡中获取连接ID：Shows stalling and no connection id

15秒后，响应加载为空 .

在chrome：// net-internals /＃events中，请求如下所示：

寻找15秒的差距，什么是铬告诉我？

Fininshed request in chrome dev tab

我已阅读了很多主题，并试图在没有运气的情况下解决问题

Chrome stalls when making multiple requests to same resource?

https://bugs.chromium.org/p/chromium/issues/detail?id=46104

https://bugs.chromium.org/p/chromium/issues/detail?id=447463

我发现的线程/问题是类似的，但解决方案不起作用，我希望有人有这种类型的问题的经验，并有任何想法
