Wrong WordPress installation. What is the problem?

Question

Digital certificates

When installing wordpress on a domain with an ssl-certificate wordpress curve from the very first installation window
As you can see, styles were not applied

. If I disable ssl, then everything is in order. What is the problem?

Usually there are no problems during installation. When switching to ssl of an existing site, there are plugins, but this is already in the admin panel of a working site, and my very first installation step is already a curve.

Answer 2
