Problem with certificates

[robinsmidsrod]

The error message you see on http://ipxe.org/err/0216eb says "no usable certificates". My guess is that you've not followed the instructions on http://ipxe.org/crypto exactly, and you don't have a proper certificate signature embedded inside your iPXE binary that is trusted that matches what the web server is sending. If you try with a normal web browser, is the correct certificate being sent to the client?

It might also be that you're using SSL virtual-hosting, and not a dedicated IP for each SSL certificate, which I believe requires support for the TLS 1.2 hostname extension. It is commonplace to be present in browsers, but I'm unsure if iPXE supports it.
