Google chrome cache on SSL?

Question

Google

Hello, we launched the site for a day for an SSL test, and as it turned out, some functions did not work, and http was returned back, but now Google Chrome has cached https by the user, and now everyone says that the site is not responding, but if you try to open via http, then throws on https (this is the cache of chrome itself). What to do? I can't enable HTTPS yet

Answer 1

We go to a special page for your browser
For Yandex.Browser: about:net-internals#hsts
For Google Chrome, Opera: chrome://net-internals/#hsts
* For Mozilla Firefox: about:permissions. Find the site, click on the "Forget About This Site" button
* For Safari: Delete the file ~/Library/Cookies/HSTS.plist
Find the input field with the name "Delete domain"
Enter the domain of the site on which you want to remove the redirect. (Format: example.ru) and click on the button next to the field.
I don’t know whether it is necessary to close all other tabs, except for the site from which the redirect is, and whether it is necessary to clear the history, it worked for me as well.

Answer 2

Probably HSTS was enabled. Disable now in no way until this header expires.
