My previous installation had issues with the TLS certificate time of issue, which was successfully fixed in this version (https://bugzilla.redhat.com/show_bug.cgi?id=1210486).

similar issue with new novnc 0.5.1 has been fixed recently. We're due updating both spice-html5 (some small improvements) and adopting python-websockify 0.6.0, it will follow in the next couple of weeks….if it doesn't make it for 3.6 GA it will be backported
