Hourly e-mail notification not working - recieving them only once per day

Hi there,

we are running a Nextcloud Hub II (23.0.3) on german hoster: all-inkl / kasserver with php 7.4.
The settings are Webcron (sometimes it says: last task run successful, sometimes it fails)
However, there is like 1 e-mail per day coming at night reporting about the file changes / added files - which we need to be sent hourly - as it is configured for the users and in admin settings

SMTP settings are correct - test mail comes in like instantly.

Also strange that we recieve the requested mail sometimes between 04-06am - but only once per day…

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

  • no - i think we started with v 22 and just recently i ran all updates hoping one might fix this issue

Steps to replicate it:

  1. install Nextcloud
  2. set e-mail notification to hourly and click notification when file as changed / shared
  3. get no notification…

The output of your Nextcloud log in Admin > Logging:

no cron job error found it in

The output of your config.php file in /path/to/nextcloud (make sure you remove any identifiable information!):
