Web Services für die Authentifizierung über SSL sind aufgrund von TLS 1.2 unter Windows Server 2012 und IIS 8 fehlgeschlagen

Es gibt eine SSL-Schwachstelle mit dem Namen POODLE, die vom Google-Team im SSLv3-Protokoll entdeckt wurde. Daher ist die Verwendung von SSLv3 nicht sicher zu verwenden. Jetzt wird empfohlen, TLS 1.2 zu verwenden. Wir haben IOS-Anwendungen, die Webservices über SSL zum Anmelden an der App verwenden. Apps begannen, als iOS 10 Fehler zu melden, da sie TLS 1.2 vorgeschrieben hatten, was zu Fehlern führt.

Ich habe folgendes Skript zum Aktualisieren auf TLS 1.2 ausprobiert, habe aber immer noch Probleme beim Anmelden.
