Problem
I’ve been trying like crazy to get to my local website at site.dev, but I keep getting redirected to https://site.dev and of course it doesn’t work because I don’t have a SSL certificate for that domain.
Solution
As of December 2017, Chrome 63, Chrome is forcing all .dev domains to be redirected to HTTPS via a preloaded HTTP Strict Transport Security (HSTS) header. The .dev TLD is an actual legitimate TLD so you will need to change your local development setup to use something like http://site.localhost .
