修正方法：「InvalidOperationException：IDX20803：Unable to get configuration from： '[PII is hidden]'」

Question

私は自分のAPIとクライアントアプリをdockerにデプロイしましたが、私が生きている間、Webアプリはapiを呼び出すことができません。次の例外が発生し続けます。

他の投稿で提案された以下の行を追加しましたが、機能しませんでした、

IdentityModelEventSource.ShowPII = true;

    System.InvalidOperationException: IDX20803: Unable to obtain configuration from: '[PII is hidden]'.

TLS 1.2を有効にすると問題が解決しました

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12
