Cron Job Not Working

[nicholaswkc]

Dear forumers, I had configured several cron jobs in opnsense web gui. My cron job is to reset the wan ip address every 15 minutes.

*/15    *    *    *    *    Reset WAN Interface    Periodic interface reset   


I tried to monitor the firewall logs and its block logs doesn't reflect the changes of wan ip address every 15 minutes. It doesn't change the wan ip address. Besides this, all my cron job doesn't take effect.

Please point me in the right direction to figure out what wrong with it.
