To add to my query, when I check my exceptions.log, I see the below error.
Not Found "
coldfusion.tagext.net.HttpTag$HttpTagNotFoundException: 404 Not Found
Are you sure the page you are running is on all the servers that the load balancers distribute traffic too?
Yes, the page is running on all servers and is load balanced. If there was an issue with that, the URL will not run when executed manually also.
The only other thing I can think of would be that you have a cfhttp tag inside the schedule that is trying to call a location that doesn't exist.
