问题描述
Azure API Management服务支持使用自建网关来实现API服务，这样APIM的所有请求都可以走在自管理的企业内网中。流量都更加安全。当根据官网文档搭建后，如果在本地环境中部署超过10个Self-host gateway，并且这些Self-host gateway的主机出口IP地址（公网IP)都是同一个的时候，就会遇见429错误： [HeartbeatError], exception: System.Net.Http.HttpRequestException: Response status code does not indicate success: 429 ().

问题解答
多方查询无果后，咨询官方。得知这个是APIM 版本限制问题，升级APIM服务的版本（Azure自动维护）后，同一个公网IP地址最大的10个连接限制问题消失。
The issue is fixed starting version 0.23.1400.0 and above
