问 GetDiscoveryDocumentAsync：“提供了无效的请求URI。请求URI必须是绝对URI，或者必须设置BaseAddress。”

EN

我已经核对了大部分的问题，但没有找到答案。

我正在尝试从身份服务器获取一个JWT令牌。

下面是操作步骤：

  var discoveryDocument = new DiscoveryDocumentRequest
                Address = "https://admin.blabla.app:5000/",
                Policy =
                    RequireHttps = false
  var auth = httpClient.GetDiscoveryDocumentAsync(discoveryDocument).Result;

我得到的错误是 An invalid request URI was provided. The request URI must either be an absolute URI or BaseAddress must be set.

DiscoveryDocumentRequest

    "Policy": {
        "LoopbackAddresses": [
            "localhost",
            "127.0.0.1"
        "Authority": "https://admin.blabla.app:5000",
        "AuthorityValidationStrategy": {},
        "RequireHttps": false,
        "AllowHttpOnLoopback": true,

    "Parameters": [],

        "MajorRevision": -1,
        "MinorRevision": -1
    "Content": null,
    "Method": {
        "Method": "GET"
    "RequestUri": null,
    "Headers": [
            "Key": "Accept",
            "Value": [

}

此代码位于windows服务上。

有趣的事实:相同的代码在不同的windows机器上工作。为什么？有什么问题吗？
