wp-encrypt certificate update fails when WP_SITEURL and WM_HOME vars = https

Hello wordpress world,

Is there a way to force HTTPS protocol for the site, while not breaking the ability for wp-encrypt to update the site certificate?

Presently, I have to do it manually by editing
/opt/bitnami/apps/wordpress/htdocs/wp-config.php

Change from:
define(‘WP_SITEURL’, ‘https://www.mydomain.com/’);
define(‘WP_HOME’, ‘https://www.mydomain.com/’);

To:
define(‘WP_SITEURL’, ‘https://www.mydomain.com/’);
define(‘WP_HOME’, ‘https://www.mydomain.com/’);

After this change, the wp-encrypt certificate update works and I can edit my wp-config.php back to HTTPS. Seems like there has to be a way to achieve my desire for HTTPS protocol (at least on the admin page authentications) plus the ability to have auto-update of site certificate for wp-encrypt.

Any advice?

Many thanks,
