On a Plesk for Linux server, scheduled tasks do not start automatically, including scheduled backup, statistics tasks or SSL certificate renewal.
If a scheduled task is started manually from Plesk, it works correctly.
cron service is stopped on the server:
# systemctl status cron.service | grep "Active:"
Active: inactive (dead) since Thu 2019-10-17 13:17:27 +07; 1s ago
Connect to the server using SSH.
Enable and start cron:
# systemctl enable crond
# systemctl start crond
On Debian and Ubuntu:
# systemctl enable cron
# systemctl start cron
