How to display Yandex map when switching to https in Bitrix?

Question

1C-Bitrix

Hello! When translating a site to https, Yandex map is not loaded in Google Chrome due to mixed content. I tried all the methods that are described in blogs and forums:

$scheme = (CMain::IsHTTPS() ? "https" : "http");- deleting this line from the component - and the address ://api-maps.yandex.ru/ is so relative.

Added at the end of the settings.php file:

'https_request' => 
  array (
    'value' => true,
  ),

In the file dbconn.php added the line $_SERVER['HTTPS'] = 'on';

Zero reaction to all actions. I cleared the cache even after each save, it's still the same as it was and remains.
