Apache Ошибка 400 При запросе через https. Как найти причину?

Здравствуйте!
Физический сервер, Debian, ISPmanager, Apache, PHP как модуль Apache.
Недавно купил сертификат, установил его через ISPManager. При переходе через my.domain — сайт открывается и работает нормально. Но при переходе через my.domain — Chrome вообще не открывает сайт, а Mozilla, Safari и другие выводят ошибку 400.

MOD_SSL — включен. Содержимое ssl.conf:

Его и vhosts менял добавляя IP сервера, работает по http в любом случае.

Запускал проверку SSL через сайты, все работает, сертификат работает при переходе в ISPmanager по адресу my.domain:1500. Но через my.domain — ошибка 400, my.domain:443 — тоже.
Порты 80 и 443 слушаются apache.
Настроено вроде верно, так что похоже в силу отстутствия опыта в этом вопросе, я что-то упускаю…
Буду рад любой помощи)
