title: MVC Redirect error in Chrome
body: <p>I've implemented mixed mode authentication in our MVC 5 application and everything seems to be working fine apart from one niggly problem.</p>
  
  <p>When I browse to the site in Chrome the following page is displayed:</p>
  
  <blockquote>
    <p>This site can’t be reached
    The web page at xxxx might be temporarily down or it may have moved
    permanently to a new web address.</p>
  </blockquote>
  
  <p><a href="https://i.stack.imgur.com/HkkGJ.jpg" rel="nofollow noreferrer">ERR_UNEXPECTED</a></p>
  
  <p>The main page is actually loaded, but I'm concerned that this might confuse users. The error doesn't appear in Firefox, IE or Edge.</p>
  
  <p>I'm assuming it's down the redirects I'm performing during the login process, but I'm not sure why Chrome is showing the error.</p>
  
  <p>The basic process is:</p>
  
  <ol>
  <li>Forms authentication process checks if user is logged in</li>
  <li>If authenticated, redirect to desired page (or default)</li>
  <li>If no, redirect to signin action</li>
  <li>Signin action then checks if single sign on is enabled, if it is then the user is redirected to an area of the site which can handle windows authentication. Otherwise they are redirected to the normal login page</li>
  <li>User is then either authenticated using windows authentication, or redirect to login page</li>
  </ol>
  
  <p>Just looking for any ideas as to why this error is only shown in Chrome</p>
