Calendars and contacts stopped showing up in apps in Nextcloud AIO v34.0.2 but are accessible through caldav/carddav

The Basics

  • Nextcloud Server version (e.g., 29.x.x):
    • AIO v34.0.2
  • Operating system and version (e.g., Ubuntu 24.04):
    • NixOS 26.05
  • Reverse proxy and version _(e.g. nginx 1.27.2)
    • Caddy 2.11.4
  • Is this the first time you’ve seen this error? (Yes / No):
    • Yes
  • When did this problem seem to first start?
    • August 1
  • Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
    • AIO
  • Are you using CloudfIare, mod_security, or similar? (Yes / No)
    • no

Summary of the issue you are facing:

I got nextcloud AIO running about a week or so ago. Everything was working fine, but then the calendars stopped showing up in the calendars app and the contacts app just keeps trying to load.

I can still access everything with caldav and carddav, but I don’t seem to be able to create new events. Edit: I was wrong. I can create events and they sync to different devices. I also forgot to mention that events show up on the dashboard correctly.

Log entries

Nextcloud

There was literally nothing in the logs, so I changed the logging level to “info” and tried to access both the calendar and contacts again.

Web Browser

My main browser is Firefox, but I’ve also tried Chromium and the same thing happened.

Web server / Reverse Proxy

There’s nothing in Caddy’s logs and nothing in nextcloud-aio-apache or nextcloud-aio-nextcloud

Configuration

Nextcloud

The output of occ config:list system or similar is best, but, if not possible, the contents of your config.php file from /path/to/nextcloud is fine (make sure to remove any identifiable information!):
