Well, I finally solved this

The solution was to include the following lines both in wp-config.php (root WP folder) and in bp-custom.php (wp-content/plugins folder)

define('WP_HOME','https://' . $_SERVER['HTTP_HOST']);
define('WP_SITEURL','https://' . $_SERVER['HTTP_HOST']);

Hope this helps someone in the future!
