所以我最近买了一个vps来尝试SignalR在我的项目中，我用了这个例子:简单的SignalR项目
不幸的是，虽然我没有这样的事情的任何经验，我上传了我的vps服务器端程序，并试图与它连接，但我得到以下错误:An error occurred while sending the request.更详细:
System.Net.Http.HttpRequestException' in mscorlib.dll
System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond ip:9080

所以我想知道我是否在这里做错了什么，或者需要在我的服务器上做任何特定的设置/设置
顺便说一下，我的目标是与服务器连接并为我的项目获取实时数据，所以如果有更好的替代方案，将非常感谢建议好吧，我找到了解决方案，我的防火墙阻止连接
