New Post: Unable to open workbook in Secure environment

I have an application which I used CLosedXMl to generate and Excel workbook in memory. I can open or download the excel workbook in firefox and chrome in all environments whether this environment uses http or https. When I use IE, I can only open the workbook in an environment which uses http and when I moved the code to QA environment where https is required, I get an error when open or downloading the workbook. The error message is "Internet Explorer cannot download xxxxxx from qa.myaccount.thomsonreuters.com.
Internet Explorer was not able to open this Internet site. This requested site is either unavailable or cannot be found. Please try again later.
Any help will be highly appreciated.
