Hello,

Can you please provide a bit more information for us to be able to help in resolving the issue

1. Is this happening on an Internet site or for an intranet site
2. Am guessing that you are exporting to a XLS, some data on a website - did that website have any specific instructions for exporting to XLS working on HTTPS?
3. When you try to export to XLS using HTTPS, are you seeing any error messages or warning messages on the site?

Based on the above we can narrow the root cause and might request you to check the errors logged in the developer console if required.

Thank you

Hi Gnittala,

Thanks..

Pls find more info in below...

In our application 'export excel' option is present in 4 different pages. Using Jquery to calling the excel. All the excels working in development environment in both IE and FF. In testing env, all the excels working fine in IE. But only 2 pages excel are working in FF in testing env. Remaining not working and 'The connection was reset The connection to the server was reset while the page was loading' error page appears when we click on 'export excel' button. More, all the Export excel option is supported in http URL but mentioned two only not supported in https using firefox. Dev server OS is windows...QA / Prod server OS is Linux. Application running on Interent site. No specific instructions for exporting data to Excel (note: same scenario working on IE & FF in Dev env)

If content is missing or otherwise not working then check if there is a shield icon on the left end side of the location bar before the "Site Identity Button" (globe/padlock) on the location bar indicating that content is blocked.
