mycroft-core: unable to register

Hi, I’ve just installed successfully mycroft with dev_setup.sh mycroft asks me to register to home.mycroft.ai. But, the add_device web page does not react when I type my id in the input box.

Javascript error : The page at 'https://home.mycroft.ai/#/device/add?_k=ri6gbz' was loaded over HTTPS, but requested an insecure resource 'http://localhost:8888/'. This request has been blocked; the content must be served over HTTPS.
