Description

[Eckard Berberich]

Steps to reproduce:
Open Calendar tab, go to File > New > Calendar, choose "On the Network".
Fill in username and Location (URL) of the iCloud calendar which would be something like
https://pXX-caldav.icloud.com/1234567890/calendars/home/
Click "Find Calendars".

Nothing happens, the turning blue circle may turn for hours, Thunderbird doesn't find the calendar.

Possibly bug 1793757

Not sure.
The issue I describe does not occur in versions 91.*, 102.0, 102.0.1, 102.0.2 nor 102.0.3.
First version where it occurs is TB 102.1.0.

Bug 1798231 is reporting another issue, but could apparently set it up fine.

Comment 7

[Andrei Hajdukewycz [:sancus]]

Seems like libc.dylib is missing or not working and so DNS fails here?

Currently running v102.7.2 and having a similar issue. The iCloud calendar I use is able to pull events created in Thunderbird, but not able to push events created in iCloud (through phone, browser, etc) back to Thunderbird.

What does this tell us exactly, that the app-specific password and caldav URL is correct but Apple has issues on it's end for incorrect authentication perhaps?

I can confirm that synchronising with or re-creating a new calendar via caldav at my posteo.de account which I had been using flawlessly for several years doesn't work anymore in TB 102.1 (v102.11 on Arch Linux here). Here's what the error console reports:

12:54:28.513 Calendar: [CalICSProvider] Could not detect calendar using method attemptHead - HTTP response status -1 CalICSProvider.jsm:94

Again, this had worked in the past without any problems. I also add that my iPhone and the KDE app KOrganizer still work flawlessly. It's obvious that something is broken in Thunderbird.

It's not an Apple issue since CalDav for iCloud works fine until TB 102.0.3 !
Beginning with TB 102.1.0 you can no longer create an iCloud CalDav calendar. Very odd :from one minor version to the next minor version it stops working.
A workaround: install TB 102.0.3 (or earlier), create your iCloud CalDav calendars, then update to the actual version.
Once installed in TB 102.0.3 your calendars will continue to work flawlessly after each update to a more recent version.

As mentioned in my post, the problem not only applies to caldav with iCloud. My calendars at posteo.de and mailbox.org aren't accessible anymore, either. They continue to work with my iPhone and with Korganizer. This is a general problem concerning caldav with Thunderbird.

Is there any chance this could be a knock-on effect from an m-c change?

Anything is possible.

You may be experiencing some other issue, possibly with 3rd party software such as antivirus/firewall.
My mailbox.org calendar seems to work just fine.

Okay, I created a new profile and could successfully add a caldav calandar. So I went back to my normal profile, deactivated tentatively uBlock Origin - and success, success: it worked! I have no idea why uBlock Origin (configured to use Dynamic Filtering in Hard Mode - see https://github.com/gorhill/uBlock/wiki/Blocking-mode:-hard-mode) would interfere with the calendar but it obviously did.

With 102.15.1 I am getting this error:
"Could not find calendars at this location. Please check your settings."

Is that because of this bug?
