I keep getting this popup in iCal: "iCal couldn't connect to p06-caldav.icloud.com after trying for 120 seconds. Make sure you're connected to the Internet, then try again later." A few calendars refresh, but some of them don't - presumably the ones that cause that message to appear. The account works OK in iCal for a few months, then every so often it gives that message for a few months, before starting to work again, without me making any setup changes. Does that mean that the problem is Apple? Is there another server I can use that doesn't time out? I am connecting to server: p06-caldav.icloud.com with server path: /143756798/principal/ (I can't even remember where I got that information from originally to set up the account in iCal) I am using iCal 4.0.4 on OS 10.6.8 My iCal works fine on my IOS 7 iPhone, and the shared calendars sync fine in my wife's iCal, so I can use the calendars OK, but just not on my laptop. Thanks!
