Do you see any other errors together with this one? I would've expected
something from the TLS/SSL parts of the code as well. You might get some
more results if you build with DEBUG=x509,validator,https. That should
tell you a bit more about what's going on.

I know that the OCSP responder on ca.ipxe.org was down for some time
some days ago, and it might've been related to that, but that should be
fixed again now. Can you still reproduce?
