Have you enabled websockets on the server?

  • On the taskbar, click Server Manager.
  • In Server Manager, click the Manage menu, and then click Add Roles and Features.
  • In the Add Roles and Features wizard, click Next. …
  • On the Server Roles page, expand Web Server (IIS), expand Web Server, expand - Application Development, and then select WebSocket Protocol.
