Nextcloud 17.0.2-0 Docker Cron error

Hi,

i installed a new Server with the newest Nextcloud App 17.0.2-0.

After a while i found out, my cron dont work. Cron never work in the Container (2 Days)

At the moment i try to find out why.

In the Nextcloud Settings the Cron didnt work over 20 minutes.

Letzte Aufgaben-Ausführung lief Vor 20 Minuten. Etwas scheint falsch zu sein.

Now i logged in the container and test the command manually:

root@nextc-61458978:/etc/cron.d# sudo -u www-data php -f /var/www/html/cron.php
root@nextc-61458978:/etc/cron.d# sudo -u www-data php -f /var/www/html/cron.php                                            
root@nextc-61458978:/etc/cron.d#

If i open the cron.php in browser, the croncheck in the settings are fine. If i use the cron command of /etc/cron.d/nextcloud it dont work.

What i done:
restart the server
restart the service
restart the docker
manally trigger the cron
open the cron.php (work manually)

On my older installation (16.0.6-0) it work fine and i cant see a difference to the newer configs.

Any ideas?

Best Regards
