Hi,
This is not really an issue with AnyConnect but rather with my CA server, but I figure out that many peoples are using a similair setup and maybe have an idee on what cause this issue. I am using both a FTD and a Microsoft server 2012 in my lab and I want to test certificate authentication.
I have installed both a root and Identity certificate on my FMC from my CA server and the last step now is to download a user certificate, but the CA server wont let me do it. When selecting to download a User Certificate from the CA server, I get the following error:

I have tried with both Chrome, Internet Explorer, MS Edge and Firefox but with the same result.
I've google the isse and many peoples have experienced the same problem, but unforuntatly I have not find a solution.
Anyone that have any idea on how I can solve this?
Thanks
