   Niedawna aktualizacja bezpieczeństwa dla aplikacji Common Runtime w regionie UE mogła nieumyślnie wprowadzić surowszą politykę dotyczącą certyfikatów TLS wykorzystywanych do zakończenia domen aplikacji TLS (.herokuapp.com). Spowodowało to, że niektórzy klienci doświadczyli awarii uścisków dłoni TLS i nie mogli połączyć się z aplikacjami. Inżynierowie zidentyfikowali problem i pracujemy nad jego naprawą.
