我对使用signalr有点陌生。我正在处理一个系统，它将从一个服务器处理多个客户端。我想为每个客户端创建一个单独的集线器，但当我添加一个新的集线器时，另一个集线器变得不可操作。
以下是我尝试连接客户端时遇到的错误：

`[2022-11-03T15:01:03.952Z] Information: WebSocket connected to wss://localhost:7178/chatHub?id=fwNf0IydU6eYjOMPq9JQsw.

ChatHub.cs如下所示：
public class ChatHub : AbpHubBase, ISingletonDependency
这些是我的终点

endpoints.MapHub<AbpHubBase>("/chatHub");
                endpoints.MapHub<ChatHubV>("/chatHubV2");
