SignalR with Office Apps - "Error Access Denied error while negotiate connection."

Question

I have three projects.

• SignalR Host Application
  • Enabled CORS and JSONP settings
• Office Apps application (manifest)
  • in the masifest > App Domains settings, included the SignalR Host Application URL
• Office Apps Web application
  • modified the $.connection.hub.url. since I am accessing cross origin host

I am accessing cross-origin SignalR Host Application from Office Apps Web application. When I start the connection from hub I got "Error Access Denied" error while negotiate connection.". But Its working in Browser (for this I have created html application with same code and run in browser).

Environment: jquery-1.10.2.js, jquery.signalR-2.2.1, Office 2016

Thanks in Advance.

Answer 1

I found the root cause. Office apps requires SSL Connection to signalR Server.

$.connection.hub.url = "https://localhost/Hub/signalr";
