Cron jobs are not triggering automatically

Your software
My PHP version is 7.4.21 :
My MySQL/MariaDB version is (delete as applicable): MySQL/MariaDB version:5.7.34

My problem is :I am first time using mautic.I have setup everything correctly and everything is working perfect.But i am facing issues with cron jobs.Cron jobs are not getting triggered automatically.

Steps I have tried to fix the problem :
1.Clear Cache
2.Cache warmup
3.Check file permissions
4.Run Cronjobs on command line,all are working.But not able to triggered automatically from crontab.

Hi, can you share your settings, maybe we can spot an error.
