caldav not working in ical under Mojave

Same problem here. I'm running a CalDAV server on a Synology NAS. Worked perfect on OS X High Sierra and iOS9 to 11.

Now with Mojave and iOS12 it's not possible to create new CalDAV account. The old CalDAV accounts are still working but creating new accounts : problem with authentication.

I tried on an old iPad with iOS9 and an old Mac mini with OS X High Sierra : it's still possible to create and use CalDAV accounts for using it in iCal/Calendar.

Anyone?

It was broken in Mojave beta already and I opened a ticket with the last beta, but so far no reaction from Apple.

I again tested with Mojave when it was officially released, but still the same.. It seems that the authentication process is buggy.

I use the CalDav Server on Synology - all Macs with older OS than Mojave works fine, only Mojave has a problem.

Same problem on my MacBook Pro after installing Mojave (10.14.1?). And the problem appears on my MacPro with High Sierra (10.13.something) and the latest security update 2018.002. My iOS11 devices are the only machines that can access calendars and remainders.

PS 2Do on the mac is still working and syncing.

Exactly the same problem here. I'm running a Davical installation on my internal network.

- The calendar of Mozilla Thunderbird and Caldavzap as a webbrowser frontend are both working fine with my Davical. So I think it's save to say that it is Apple's fault.

- My iMac running 10.13.6 was also working fine until Apple screwed up with the security update 2018-002. Yes, I can exactly pinpoint the problem to his update.

- My Macbook Air has never worked with my Davical under Mojave 10.14.1. I don't know if it was fine under 10.14 since I've never opened the calendar app on it before the .1 update.

It doesn't matter how I try to enter the settings in manual or advanced mode. It just fails adding the account.

I have an Owncloud Server running as a calDAV Server. Since the OS-X 10.14 update I cannot access my calenders anymore form iCal. They don' t sync. Same problems with my iPhone since the last update. On mac I have deleted the account and reentered it. The connection works I can see my calenders (the names) in ical, but all the entries don't sync. "The server responded with “500” to operation CalDAVAccountRefreshQueueableOperation".

I have tried fantastical yet. I works perfectly, no problems with my calDAV server so far. This really seams to be a calDAV problem of the lastest mac- & iOS . I desperately need a solution for my iphone to get my reminders back.

I have Radicale (https://radicale.org/) as CalDAV-server on a Raspberry Pi. After updating my laptop to Mojave I could not sync with the calendars on the server anymore; can't remember the error message. So I deleted the calendars on the laptop. But now I can't even add the server's calendars anymore; something like "could not verify user/password".

So, I updated to Mojave on my MacPro, too, because after the Security Update syncing failed as well. Now, I can't sync my still existing calendars with the calendars on the server: "can't verify user/password"...

I have the same problem since upgrading to Mojave. I'm only minorly-computer literate so not sure how to fix it.

My error message:

"The request (CalDAVMigrateToServerQueueableOperation) for account “iCloud” failed."

Hopefully Apple will fix it!

Have the exact same problem here.

Fantastical sounds great but it's 70$. I like the Calendar from Apple but if it doesn't work anymore... :/

By the way we are using Sogo.

Still looking for a free calendar app.

Hi domce84,

I've the same issue: since mojave upgrade no synchronization with my CalDAV synology server!

What do you mean about Synology last version (which one?)?

Is there a new protocol in Calendar that Synology CalDAV server now implements?

Thanks a lot.

Of course. Apple imposes SSL for connexions to caldav servers with its native app (on macOS or iOS). So the only solution, beside using an other app, is to have a server with https. That's what we will working on here : installing a SSL certificate for our SOGo server. Pretty sure it will work after that.

Yes, as others pointed out syncing works if SSL is enabled and working - but SSL is optional, not mandatory.

Finally, I enabled SSL on the Radicale server (I tried to enable SSL for lighttpd several times, which did not work and is the wrong way). Then I still have to visit the web front-end (https://<server-name>:5232) to accept the self signed certificate and voila - calendar and address book sync after adding new accounts with SSL. :-)

I cannot seem to get this working either. I have a Synology DiskStation 916+ running DSM 6.2.1-23824 Update 1 with the WebDAV 2.3.4-0025 package installed and running without apparent error. I have a signed certificate for the FQDN of my DiskStation installed and enabled for the WebDAV service. I have tried the Apple Calendar app as well as Fantastical 2 which I also own (using multiple different ports, advanced setup, etc...). I can reach the DiskStation from the internal network and from the external network over http and https. I was hoping to replace my macOS Server app with the Synology but I can't get mail server or CalDAV working. Well, I got outgoing mail working but not incoming. And yes, the firewall ports are open. I'm sure it is something I am not doing correctly but dadgummit! I've spent the better part of a day trying to get this working without success. I will try contacting Synology support tomorrow but the Synology forums seemed not to have any solutions either and those that contacted support were referred to Apple.

No luck here. I've added (self-signed) HTTPS to my Apache2 hosting my Davical.

I opened the webserver with Safari so that my SSL-key gets added to the keychain.

Opening https://myserver.local/davical/caldav.php/Username/calendar in Safari: After entering the credentials the server offers an .ics file as a download.

Entering the the above stuff in the advanced settings for a new account of the calendar: There's no more error when clicking "Ok". But I can't see the calendar in the normal window afterwards.

And this behavior is still there after the latest security update for 10.13.6. I haven't tried my 10.14.2 Macbook. But my guess is it's equally bad.

extend :-)

Since the port 443 is open and routed to the SYNO you should use the extended settings with server IP and path as "/caldav/'your_user_on_syno'" with port 443 in the account settings in Mojave for a Caldav account.
