In some versions of websockify and the relates noVNC versions that use it
I've seen the same behaviour. This is due to the way websockify tries to
detect the protocol to use. It ends up doing a localhost connection and the
browser rejects it as an unsafe operation.

It was fixed in later versions of websockify.

Have you tried manually updating the NoVNC and websockify files to later
versions from source?
