Cron does not work

I’m sorry, I don’t speak English well.
I can only describe it simply.
centos7+nginx+php70+nextcloud13.0.2
selinux = enforcing

Cron it doesn’t work

ssh

semanage fcontext -l

getsebool -a | grep cron

cron log

Now I have to close the Cron timing task of Selinux.Nextcloud to work properly.

I would like to say thank you in advance for any help.
