【问题描述】：
之前：Service-A ===> Service-B（正常工作https）
现在：Service-A ===> Service-B（结束http）
我已确定 service A 已配置为使用 http 进行请求，但出现以下错误：
[2019-09-02 02:15:11,579] ERROR in app: Exception on /api/users [POST]

如果我将协议设置回 https，我会收到 Unknown SSLProtocol 错误，因此 Service-B 肯定在 http 上。
User-Agent 标头设置正确。我尝试将其修改为空标题和web browser 标题，但似乎没有任何影响。
错误似乎是间歇性发生的，并且错误的频率各不相同。
请求版本：2.18.4
【问题讨论】：
-
您可以使用 Postman 或 Insomnia 之类的方式在
/api/users上POST请求吗？那么你通过 http 得到了什么？ -
抱歉回复晚了。我已经设置了 Postman 并针对实例发出了 GET 请求。看起来有些实例是响应式的，有些则不是。可能是因为移除了负载均衡器，但我还不确定。

邮递员错误
Could not get any response
