How to stop an automatic redirect from “http://” to “https://” in Google Chrome

For example :

 If You want to access this url http://test.example.com.vn/everything : you will type url in Google Chrome like that: test.example.com.vn/everything but Chrome auto switch to https://test.example.com.vn/everything but your server didn't open port 443 for subdomain : test.example.com.vn so It will return :Failed .

To resolve this problem : 

1. you go to : chrome://net-internals/#hsts

Note : you don't need to query subdomain: test.example.com.vn  , only domain not subdomain .

3. Input domain example.com.vn into below box : "Delete domain security policies" then click to Delete ,Done ! 

That's All !
