localhost blocked on Chrome with "Privacy Error"

It worked for me just by changing " .dev" to ".local" I'm using windows 10

From Chrome version 63, it will redirect all .dev extension to domain https So try another extension to another, ex .test, .local... You can refer here: https://docs.serverpress.com/article/234-your-connection-is-not-private-google-chrome

Try this:

In Chrome, put in chrome://flags/#allow-insecure-localhost in the address bar.

Enable the option that says "Allow invalid certificates for resources loaded from localhost".

Restart Chrome, and it should allow the site.

Try typing in your are blocked page thisisunsafe. Simple type this word on keyboard. I found solution from this https://medium.com/@dblazeski/chrome-bypass-net-err-cert-invalid-for-development-daefae43eb12
