Where do you test the signalr, under the same LAN? I think the 'ws://localhost/chatHub' shouble be changed to a specific ip.

Could you please tell me which server you have hosted your web application on windows 10 or server 2012? Since the url is localhost that means it connect to the local's application. Which url you have used in your browser? Do you mean you want to access the signlar application which is hosted on the local-side?
