Can't subscribe to googlecalender

[marko.ramius]

Hi,
I'm using Open Xchange Version 7.4.2 Rev6.
Whenever I try subscribing to a googlecalender in calender app I just get the message "Error: The login or password you entered are wrong". I've tested this with several accounts and with 2factor-authentication enabled and disabled. Is there some package I'm misssing?

Thanks in advance

If you see the functionality in the UI there shouldn't be anything missing.
Do you have a more complete error message including stacktrace in the open-xchange logfile?
