[Troubleshooting] How to fix opening ASUS Router WEB GUI appears “Your connection is not private”

When you try to connect to ASUS router via HTTPS in a browser, it may give a warning message “Your connection is not private”. It represents this secure certificate of the website is not trusted. The default certificate in the router is self-signed and doesn't fulfill the default SSL policy of the browser.
