Citrix Director home page does not get loaded after authentication. It just stuck on the page with loading spinning wheel.

No errors are displayed on the web page. 
Event ID 4648, 4624 and 4672 are logged under Security Event log.
Event ID 4624 states: An account was successfully logged on.
 

1. On Citrix Director server, update web.config file located in "C:\inetpub\wwwroot\Director" with following content.

   <system.serviceModel>
       <serviceHostingEnvironment multipleSiteBindingsEnabled="true" aspNetCompatibilityEnabled="true" />

2. If X-Frame-Options custom header is enabled, update the web.config file with following.

   <httpProtocol>
      <customHeaders>
        <add name="X-Frame-Options" value="ALLOW-FROM http://localhost/director/default.html" /> ​
     </customHeaders>
   </httpProtocol>

    

Note: These two entries are needed only if IIS MultiSiteBinding is enabled and X-Frame-Options custom header is configured. In a single domain/single site environment, only step 1 is needed.

Caution!

In a single domain, enabling the "multipleSiteBindingsEnabled may cause a "Server Error in '/Director' Application" error when trying to open the Citrix Director Logon page. It is recommended to enable "multipleSiteBindingsEnabled" only in an IIS environment with multiple sites and multi domains.
