How to force IIS not to redirect from HTTPS to HTTP?

Question

IIS

Set up a binding for the site on HTTPS. But when you go to https://domain.com , it redirects to http.
In web.config ssl is enabled

<add key="SSLIsAvailable" value="true" />
<add key="SSLIsRequiredByWebServer" value="true" />

Somewhere there is a redirect, but I don’t understand where. If IIS is forced to redirect to HTTPS, it gives an error that a cyclic redirect has occurred.
Tested in incognito mode.

Look in the settings of your hosting provider.
For example, Plesk has a "Preferred Domain" setting that will redirect visitors with an HTTP 301 code. If this setting is selected, it does not appear in Web.config in any way.
