Normalerweise funktioniert die Verwendung von Google OpenId tausende Male am Tag, dann läuft es zeitweise schief und läuft für ungefähr eine Stunde aus (einige Anfragen werden validiert, aber nicht alle). Wiederholte Validierung wird eventuell funktionieren.

Fehlermeldungen sind:

<code>Event code: 200000 
Event message: No OpenID endpoint found. : https://www.google.com/accounts/o8/id
