HSTS Attack and my site does not works

Hi, I have just managed to set my site up following this tutorial: [Support Guide] DNS Quick Start - How to set up DNS

But now, If I try to enter the site, I go to the site (gasofatracker.com or www.gasofratracker.com) and have this alert:


It is in Spanish but basically it says that the connection is not safe and they might be trying to get my data or something. It also says something about HSTS.

What can I do?

Please do not open duplicate threads for the same issue, as it slows down our response time. We’ve followed up in the original thread. Thanks.
