Chrome 63 redirects .dev domains to HTTPS via HTTP Strict Transport Security (HSTS) header.

What should we do?

A quick workaround would be to rename your .dev sites to .test or .localhost. I recommend the second, as *.localhost sites automatically open as You don’t need to add site.code to /etc/hosts. So, if your site was you should rename it to site.localhost.
