Ошибка перенаправления HTTPS для некоторых URL-адресов, но не для других

Перенаправление с HTTP на HTTPS происходит правильно когда URL-адрес является одним из следующих:

• http://example.com >> https://example.com [ХОРОШО]
• http://www.example.com >> https://example.com [ХОРОШО]
• http://www.example.com/login >> https://example.com/login [ХОРОШО]

Однако перенаправление на HTTPS терпит неудачу когда URL такой:

• http://example.com/login >> ошибка (см. скриншот)

Посоветуйте, пожалуйста, как решить.

Код и конфигурация ниже. Заранее спасибо...
