Q: Public iCloud calendars suddenly require username and password
I've got a couple of calendars shared public from iCloud. They have been working great for some years now.
But approximately a week ago the users subscribing to them reported that they no longer update.
I tried to unshare and share again, to see if that worked. Also made some of the users delete the subscription and add it again.
The problem now is that they can't be added!
Calendar.app now suddenly prompts for a username and password for subscribing to my public calender!
I tried with some random characters for user and password but then it just prompts again.
I then tried with my apple-id and then I got an error message instead saying that the calendar cannot be found on the address.
I'm running OS X 10.10.5 with Calendar.app Version 8.0 (2034.9)
I've also tried sharing and adding the calendar from iCloud.com and from my iPhone 6S running iOS 10.02 but with the same result.
This seems to be a bug in iCloud - can somebody else try to share and subscribe to an iCloud-calendar to see if this happens to everybody or just me?
Is Apple aware of this bug?
MacBook Pro (Retina, 15-inch, Mid 2014), iOS 10.0.2

Turns out I was a bit sloppy with my testing... The calendar I activated from icloud.com actually works again!
I've talked with the apple support about the issue and they didn't know the reason behind why my links stopped working. It seems that in OS X 10.10 or older, the link generated from calendar.app is faulty and won't work any more.
Not sure if this is the true reason but anyhow, the solution was to log in to icloud.com, disable public sharing on your calendars and then activating it again.
The downside is that doing this generates a totally new link, so you have to notify all subscribers to update their links to your calendar.
EDIT: I also made this reply from the wrong account - If any is confused right now, this is OP, Tisse writing this reply on how I solved the issue.
