c# - 使用 mongodb.driver 2.10.3 连接到 mongodb 服务器时出错

Question

我尝试为我的集群使用 mongodb 连接方法，但出现超时错误。集群有 3 个分片（00、01、02），根据我的 mongo 仪表板，它们都很健康。我还可以看到在主分片上注册了读取操作。无论我运行什么查询，我都会得到相同的超时异常。

var client = new MongoClient("mongodb+srv://bugbeeb:*******@csharptest-yzm6y.mongodb.net/test?retryWrites=true&w=majority");
var database = client.GetDatabase("test");
database.ListCollectionNames().ToList();

未处理的异常。System.TimeoutException：使用 CompositeServerSelector{ Selectors = MongoDB.Driver.MongoClient+AreSessionsSupportedServerSelector, LatencyLimitingServerSelector{ AllowedLatencyRange = 00:00:00.0150000 } } 选择服务器 30000 毫秒后发生超时。集群状态的客户端视图是 { ClusterId : "1", ConnectionMode : "ReplicaSet", Type : "ReplicaSet", State : "Disconnected", Servers : [{ ServerId: "{ ClusterId : 1, EndPoint : "Unspecified/csharptest- shard-00-00-yzm6y.mongodb.net:27017" }"，端点：“未指定/csharptest-shard-00-00-yzm6y.mongodb.net:27017”，状态：“断开连接”，类型：“未知” , HeartbeatException: "MongoDB.Driver.MongoConnectionException: 打开与服务器的连接时发生异常。---> MongoDB.Driver.MongoConnectionException：从服务器接收消息时发生异常。---> System.IO.EndOfStreamException：试图读取流的末尾。在 MongoDB.Driver.Core.Misc.StreamExtensionMethods.ReadBytesAsync(Stream stream, Byte[] buffer, Int32 offset, Int32 count, TimeSpan timeout, CancellationToken cancelToken) 在 MongoDB.Driver.Core.Connections.BinaryConnection.ReceiveBufferAsync() ---内部异常堆栈跟踪结束 --- 在 MongoDB.Driver.Core.Connections.BinaryConnection.ReceiveBufferAsync(Int32 responseTo, CancellationToken cancelToken) 在 MongoDB.Driver.Core.Connections 的 MongoDB.Driver.Core.Connections.BinaryConnection.ReceiveBufferAsync() .BinaryConnection.ReceiveMessageAsync(Int32 responseTo, IMessageEncoderSelector encoderSelector,1.ExecuteAsync(IConnection connection, CancellationToken cancellationToken) at MongoDB.Driver.Core.Connections.IsMasterHelper.GetResultAsync(IConnection connection, CommandWireProtocol1 isMasterProtocol, CancellationToken cancelToken) at MongoDB.Driver.Core.Connections.ConnectionInitializer.InitializeConnectionAsync(IConnection connection, CancellationToken cancelToken)
