Hi Guys,

I'm in the process of moving an old Apache2 server to nginx 1.13. One site we have uses SSL Client Certificates. They are being requested by the webserver and the browser supplies these.

Everything seems to work on my Mac with Safari, Chrome and Firefox.

Now on Windows all those browsers work too. Only Internet Explorer and Edge don't. Both browsers ask the user which client cert to use, I select the same one as I did with Chrome etc. but it doesn't seem to send them to nginx.

When adding some more logging params to nginx (like $ssl_client_serial) I see that no serial is being forwarded on IE/Edge but it is being forwarderdfor all other browsers, both on Mac and Windows 10.

Does anyone have any clue as of why? I've been Googling for hours but to no avail. Also tried nginx 1.10, no change.

The relevant part of my config can be found here: https://kopy.io/0ikPF#mF7Cq0IdeFDKJQ

Thanks,
