WCF：“无法打开 System.ServiceModel.Channels.ClientReliableDuplexSessionChannel”
我目前有一个带有回调合约（双工）的 WCF 服务，当我在我的计算机上使用使用它的应用程序时，一切正常，但当我从另一台计算机上尝试它时，它无法连接。
一旦我切换到使用此 wsDualHttpBinding （用于回调），这些问题就开始出现，因为当我使用 wsHttpBinding 时，一切工作正常。
为什么 Web 服务不接受其他计算机的请求？ 是否需要修改一些托管设置？
至于日志，我得到这些：

打开操作未完成 在指定的超时时间内 00:01:00。 分配给这个的时间 操作可能是某个操作的一部分 更长的超时时间
无法打开 System.ServiceModel.Channels.ClientReliableDuplexSessionChannel
有故障 System.ServiceModel.Channels.ClientReliableDuplexSessionChannel
有故障 System.ServiceModel.Channels.ServiceChannel
打开失败 System.ServiceModel.Channels.ServiceChannel
我的路由器上的端口已打开（TCP 和 UDP），因此这不是问题。
关于服务属性，这就是我正在使用的：
接口：
[ServiceContract(Name = "MusicRepo_DBAccess_Service",
CallbackContract = typeof(IOnlineUsersCallback),
SessionMode=SessionMode.Required)]
服务：
[ServiceBehavior(
ConcurrencyMode=ConcurrencyMode.Reentrant,
InstanceContextMode=InstanceContextMode.Single)]

至于Orion Edwards'帖子：
- 没有防火墙
- 参见第1点
- 是的我可以，因为我在路由器上转发了端口，所以
- 我使用 IIS 来托管服务器。
问题是，当我从 wsHttpBinding （工作正常）切换到 wsDualHttpBinding （因为我需要回调）时，这个问题就开始发生
[更新]
我现在已从 wsDualHttpBinding 切换到 NetTcpBinding，由于某种原因，一切正常。
我已经使用这篇文章来帮助我在 IIS 上设置托管，谢天谢地，一切都很好按预期工作，带有回调。
I currently have a WCF Service with a CallBack Contract (duplex), and when I use the application that makes use of it on my computer everything works fine, but when I try it from a different computer, it doesn't connect.
These problems started occurring once I switched to using this wsDualHttpBinding (for callbacks) because when I used wsHttpBinding everything worked fine.
Why is the web service not accepting requests from other computers? Is it some hosting settings that need to be modified?
As regards the logs, I am getting these:

The port is open on my router (both TCP and UDP) so that is not the issue.
As regards the Service Attributes, this is what I'm using:
Interface:
[ServiceContract(Name = "MusicRepo_DBAccess_Service",
CallbackContract = typeof(IOnlineUsersCallback),
SessionMode=SessionMode.Required)]
Service:
[ServiceBehavior(
ConcurrencyMode=ConcurrencyMode.Reentrant,
InstanceContextMode=InstanceContextMode.Single)]
[Update]
As regards Orion Edwards' post:
- No Firewall
- See point 1
- Yes I can, because I have the port forwarded on my router
- I'm using IIS to host the server.
The thing is, this problem started happening when I switched from wsHttpBinding (which was working fine) to wsDualHttpBinding (because I needed callbacks)
[Update]
I have now switched from wsDualHttpBinding to NetTcpBinding and for some reason, everything is working fine.
I have used this article to help me set up hosting on IIS, and thankully everything is working as expected, with callbacks.

如果您发布服务器和客户端配置设置，将会有所帮助。
以下是 MSDN 中 wsDualHttpBinding 工作原理的摘要（强调我的） :
It would help if you posted the server and client configuration settings.
Here's a summary of how the wsDualHttpBinding works from MSDN (emphasise mine):
要检查的事项：
