【Azure API 管理】APIM Self-Host Gateway 自建本地環境中的網關數量超過10個且它們的出口IP為同一個時出現的429錯誤

問題描述

Azure API Management服務支援使用自建網關來實作API服務,這樣APIM的所有請求都可以走在自管理的企業内網中。流量都更加安全。當根據官網文檔搭建後,如果在本地環境中部署超過10個Self-host gateway,并且這些Self-host gateway的主機出口IP位址(公網IP)都是同一個的時候,就會遇見429錯誤: [HeartbeatError], exception: System.Net.Http.HttpRequestException: Response status code does not indicate success: 429 ().

【Azure API 管理】APIM Self-Host Gateway 自建本地環境中的網關數量超過10個且它們的出口IP為同一個時出現的429錯誤

問題解答

多方查詢無果後,咨詢官方。得知這個是APIM 版本限制問題,更新APIM服務的版本(Azure自動維護)後,同一個公網IP位址最大的10個連接配接限制問題消失。

The issue is fixed starting version 0.23.1400.0 and above
