HappyLager Demo Site Forcing 'https://' on XAMPP
The issue here is actually the use of the TLD .dev. Google now owns that extension and in Chrome (which later, other browsers including Safari and Firefox enforced) it now forces the URL to go over SSL. If you don’t want to deal with all that self-signed certificate stuff to get SSL working locally, your best bet is to just switch the extension to something like .test and it should work just fine.
