SSL login with page hiding

Hi, guys.

I didn’t use SSL login page before, just changed login page slug. I set SSL certification up on Apache and added ‘FORCE_SSL_LOGIN’ in wp-config.php. But changed login page shows 404 not found.
If I deactivate hide login area(using ‘wp-login’), no problem to access login page with ‘https’.

How can I access login page with ‘https’ using chaged login page slug?

Any solutions?
