Blazor Server-side doesn't start with Windows Authentication on Chrome

Describe the bug

The server-side Blazor application doesn’t start when the authentication is set to Windows Authentication in Google Chrome. Creating an application without authentication works fine.

To Reproduce

Steps to reproduce the behavior:

1. Create a new Blazor server-side application with Windows Authentication
2. Start the application in IIS Express and open the application in Chrome.
3. You’ll see the pre-rendered page and in the top-right the username of the current Windows user is shown: Hello, DOMAIN\user!.
4. Go to the page ‘Counter’.
5. When you try to click the button ‘Click me’, nothing happens.

Additional context

I’ve tested in the following browsers with Windows Authentication enabled:

Browser	Is working?
Chrome	No
Internet Explorer	Yes1
Edge	Yes
FireFox	Yes

¹ IE only works with https://github.com/Daddoon/Blazor.Polyfill added.

---

Some points that I found that might be handy:

1. By removing the line Html.RenderStaticComponentAsync<App>() in _Host.cshtml you’ll notice that the page is white. The content that you see is pre-rendered.
2. Chrome and Internet Explorer does authenticate automatically but FireFox and Edge does not
   (I need to provide my username and password).
3. In Chrome, the WebSocket connection is established: but no data was sent:
4. In FireFox everything works fine:
