Could it have something to do with the NGINX Proxy Manager and Let's encrypt certificates?

I'm not sure if my problem is the same or related to this:

I can for sure subscribe to my (shared and private) Nextcloud calenders in MS Outlook (outlook.office.com as well as Outlook App on MacOS and also shown via Calender on iOS with this account). But every update on my NC calendars are not synchronized to Outlook since an unknown time (weeks, maybe months?)!

I'm 100 percent sure that "before" I also got every update my wife and my kids made in our shared NC calender in my Outlook calender.

Is this really an error/problem in NC or in Outlook (this is not the first and not the only of my many problems in the past with this Outlook calender on MacOS and iOS!)? I will also open an issue with my company account at MS for this.

I'm always on latest stable version due to daily patching/docker-pull.

Anything is possible.

What happens when you run curl -i {the_full_url}?

And what appears in your proxy, web server, and Nextcloud logs when you try to add to Outlook?

I had a lot of problems with subscribing to my nextcloud calendar from Google calendar and outlook. I finally narrowed it down to a troublesome calendar entry (never was able to figure out which one) that was causing the import of the exported file to fail. I deleted a bunch of old calendar entries and tried again and it started working and has been working fine since.

I know this is not a very specific report and it makes it impossible for anyone to fix any bugs if they exist but I wanted to document my experience.

Meanwhile my problem (every update on my NC calendars are not synchronized to Outlook since an unknown time) is almost solved - it just takes much longer than in the early days of the integration; but it syncs. Must be more patient now… 🤷🏼‍♂️

There is a setting which determines how often nextcloud “exports” the file for synchronization, have you loooked into that? I set it to export every hour. I can find the details for you if that helps.Marcos*Sent from my iPhoneOn Aug 13, 2024, at 10:36, Thomas Merz @.***> wrote: Meanwhile my problem (every update on my NC calendars are not synchronized to Outlook since an unknown time) is almost solved - it just takes much longer than in the early days of the integration; but it syncs.
