Cannot open Cognos reports on home page report tabs on Google Chrome after applying Cognos fix pack 10.2.2.2

Resolving The Problem

In order to resolve this, you need to configure the Cognos gateway to trust OpenPages web site by updating the HTTP response headers.

1. When the cognos gateway is run on Apache or IBM HTTP Server
• Open httpd.conf file for the server
• Append the following 3 lines where you need to substitute the URL with your OpenPages external URL ( without path ):

LoadModule headers_module modules/mod_headers.so Header always set Content-Security-Policy "frame-ancestors 'self' http://<opserver name>:<opserver port>/;" Header always set X-Frame-Options "ALLOW-FROM  http://<opserver name>:<opserver port>/"

Note that you cannot include upper case characters in the <opserver name>. Use lower case characters instead.
• Save the file and restart the server
2. When the cognos gateway is run on Internet Information Server
1. Append Content-Security-Policy header
• Open Internet Information Service(IIS) Manager
• Navigate to the Web Site node for the cognos gateway
  
• Double click HTTP Response Header feature
• Select Add… from Actions panel
• Set values like here:
1. Name : Content-Security-Policy
2. Value : frame-ancestors 'self' http://<opserver name>:<opserver port>/;
   
   where you need to substitue the URL with your OpenPages external URL ( without path ). Note that you cannot include upper case characters in the <opserver name>. Use lower case characters instead.
2. Update X-Frame-Options header
• Install URL Rewrite extension to IIS. It is downloadable here:
  https://www.iis.net/downloads/microsoft/url-rewrite
• Open Internet Information Service(IIS) Manager
• Navigate to the Web Site node for the cognos gateway
• Confirm URL Rewrite feature is available and double click it
• Select View Server Variables… from Actions panel
• Add a server variable : RESPONSE_X-Frame-Options
  
• Select Back to Rules from Actions panel
• Select Add Rule… from Actions panel
• Select Outbound rules > Blank rule and click OK
• Assign name to the rule such as x-frame-options
• Fill the rule like the following example:
  
  Note that substitue the hostname, port number in the Action properties value with your OpenPages external URL. Note that you cannot include upper case characters in the hostname. Use lower case characters instead.
• Restart the Website from the Actions panel
