Admin SSL redirect error

I managed to fix the too many redirects error by someone’s suggestion to add to the wp_config:

define( ‘WP_HOME’, ‘https://tei.ma’ );
define( ‘WP_SITEURL’, ‘https://tei.ma’ );

However I do note it is http and not https, should I care?

Also adding either the below two lines or the whole batch of code below breaks

define( ‘WP_HOME’, ‘https://tei.ma’ );
define( ‘WP_SITEURL’, ‘https://tei.ma’ );

/* SSL Settings */
define(‘FORCE_SSL_ADMIN’, true);

if( strpos($_SERVER[‘HTTP_X_FORWARDED_PROTO’], ‘https’) !== false )
$_SERVER[‘HTTPS’] = ‘on’;
else
$_SERVER[‘HTTPS’] = ‘off’;

For context, I am using cloudflare, and the errors started after troubleshooting with healthcheck (wanted to have a check in place and see what it got me…) and adding as to its request wp_super_cache. (Currently all plugins are deactivated to fix the error)
