HTTPS - unrecognised algorithm

[mastacontrola]

I could be wrong, but what are the build parameters you're using to build your binary boot files?

I believe, you still need the CA Chain or something for iPXE to recognize it as being valid. Even though they're "real" I don't think the iPXE binaries have a default set of "trusted root authorities" built into them as I imagine it would significantly increase the size of the compiled files.

Again, this is just speculation, I don't have a means to test/verify this to further help you out so maybe one of the Devs of iPXE can help shed some light as well?
