C# .Net Core，Eventhub:身份验证失败，因为远程方已关闭传输流

我正在开发EventHub的制作人。在部署到我们的测试环境后，它在本地工作正常-我收到错误“身份验证失败，因为远程方已关闭传输流。”

Docker image:mcr.microsoft.com/dotnet/core/aspnet:3.1

使用的代码：

await using (var producerClient = new EventHubProducerClient(connectionString))
                {
                    var eventData = new EventData(Encoding.UTF8.GetBytes(JsonConvert.SerializeObject(message)));

                    var batch = await producerClient.CreateBatchAsync();
                    batch.TryAdd(eventData);
                    await producerClient.SendAsync(batch);
                }

ServicePointManager.SecurityProtocol |=SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls；

有一些未提及的重要信息-通过Kubernetes在docker中部署了服务

此错误与我们公司的内部防火墙设置有关。

这看起来肯定是服务拒绝了连接，但我不确定原因。您介意分享生产者是如何创建的吗？我想了解传输是为TCP还是为WebSocket设置的。producerClient=new EventHubProducerClient（连接字符串），因此我希望使用默认tcp连接谢谢。您的假设是正确的；tcp被用作默认传输。不幸的是，由于这似乎是在服务中发生的，因此我无法从客户端的角度提供太多的见解。我将与Event Hubs服务团队跟进，并要求他们提供帮助。您有吗是否有可能启用了IP筛选器或VNET？azure portal帐户中没有IP筛选器或VNET配置，其配置接近默认值。以前我对公司防火墙有问题，但在这一阶段我得到了System.Net.Sockets.SocketException（现在已修复）。
