Microsoft C#.NET YARP 504网关错误和故障转移

我正在使用Microsoft C#NET作为ASP.NET核心Web API（最新版本）前面的API网关。 YARP用于实习生重定向到许多微服务

问题:

对于从swagger UI执行超过约2分钟的请求，我面临504 http API网关错误。如何设置增加的超时

例：https://URL/swagger/index.html =>执行POST函数=>YARP\U API\U网关=>服务\U API\U端口

2.如果内部服务目标（端点）因任何原因关闭，如何配置到另一个目标的“故障切换”？

例：配置：

   "ReverseProxy": {
    "Routes": [
      {
        "RouteId": "Service1",
        "ClusterId": "ServiceCluster1",
        "Match": {
          "Path": "/api/Action1/{**rest}"
        },
        "Transforms": [
          { "RequestHeadersCopy": "true" },
          { "RequestHeaderOriginalHost": "true" }
        ]
      },
      {
        "RouteId": "Service2",
        "ClusterId": "ServiceCluster2",
        "Match": {
          "Path": "/api/Action2/{**rest}"
        },
        "Transforms": [
          { "RequestHeadersCopy": "true" },
          { "RequestHeaderOriginalHost": "true" }
        ]
      ],
    "Clusters": {
      "ServiceCluster1": {
        "Destinations": {
          "ServiceCluster1/destination1": {
            "Address": "http://localhost:5001/"
          },
          "ServiceCluster1/destination2": {
            "Address": "http://localhost:5002/"
          }
        }
      },
      "ServiceCluster2": {
        "Destinations": {
          "ServiceCluster2/destination1": {
            "Address": "http://localhost:5003/"
          },
          "ServiceCluster2/destination2": {
            "Address": "http://localhost:5004/"
          }
        }
      },
  }
