The issue you are facing:
Another user sharing his calendar readonly to me, has a task. When synchronizing the calendars (including tasks) via davx to my phone, I get “Synchronization error: HTTP 404 Not found”.

Is this the first time you’ve seen this error? (Y/N): Y

Steps to replicate it:

  1. User shares calendar including tasks readonly
  2. I connect to all calendars via DavX on my mobile device
  3. After some time I get theses errors shown

Output errors in nextcloud.log in /var/www/ or as admin user in top right menu, filtering for errors. Use a pastebin service if necessary.

I’m not shure where to post this, in nextcloud or somewhere for DavX. I haven’t found any support board or possibility to report a Bug for DavX, so I try it here.

I can just Hide all synchronization errors on my Android device for DavX - but this shouldn’t be the solution.

Thanks for help. I’m sure this information is not enough. Thanks for any help and let me know what information I need to deliver.
