enable TLS security in a VM

Hi, I'm trying to enable TLS security for remote accesson a virtual machine with openSUSE 13.1, but after I created the CA and signed the keys, when I try to get I obtain "protocol error", even when I test on the localhost.

I've done tests on virtual mchines on my computer and I do not aprece  the same problem and I don't have any idea  about what is the problem.

Thanks
