We have an application that downloads https://www.rba.gov.au/rss/rss-cb-exchange-rates.xml daily to get exchange rates. It stopped working a few days ago, we found that above URL doesn't open in IE while it does in Chrome.
My understanding is that the App, which is developed using .NET framework, would certainly use the same thing under the hood as IE, thus it couldn't download the file either.
Below is the error I get when visiting the site using IE, I'm sure that all TLS version are enabled:
Then I tested the url using ssllabs.com and got the following result. It says fatal error is ruturned if client is IE11/Win 8 (I believe Windows 2012 and Windows 8 belong to the same family, so fatal error would occur to server 2012 too).
But I'm thinking there must be something I can do, some setting I can change to fix this issue? I would like to avoid Upgrading the OS to server 2016 just for this issue. Your help is greatly appreciated.
