my cron job isn't working

I've tried the online chat route and got referred to submit a ticket. I submitted a ticket and was told support doesn't provide coding assistance (it's a cron job???). Support referred me to the community...

I'm trying to get an Akeeba Backup cron job set up and it's not working. I've used this same cron job on another site with no problems (both sites are on the same VPS)--can someone tell me what I have wrong here? The working cron job is exactly the same as the one that's not working, except for the domain name, key, and Joomla user ID number (and the working cron is not SSL, the non-working cron has an SSL). Here is the cron that's not working (I've removed the domain name, key, and Joomla user ID number):

wget --max-redirect=150000 "https://DOMAIN/index.php?option=com_akeeba&view=backup&key=HIDDEN&profile=JOOMLA_ID" -O - 1>/dev/null 2>/dev/null

Thanks in advance for any input!
