I just set up an EC2 server, running Windows/IIS and happily used certifytheweb to get a SSL certificate.
It works well, almost everywhere. Except for one PC which also just so happens to be in a classroom where I teach. (Sigh, that’s a very visible place for the error to crop up!)
On that one special machine I get “this certificate cannot be verified up to a trusted certification authority”
And - on that one machine - I do not see:
Ensures the identity of a remote computer
I suspect that the problem is that this one problematic PC does not support IPv6, hence the problem verifying up to the CA.
Does that make sense? Is there any improvement I can make server-side (e.g. generate a new cert) that would support systems that were exclusively on IPv4?
Or… if you think I misdiagnosed the problem… let me know what you think the problem really is.
