I have a series of scheduled tasks that all run at various times of the day. Since the migration from Coldfusion version 7 to 10, these tasks have stopped running.
When I check the box, that outputs the results to a file, I get a text file that says nothing more than "Connection Failure". I have tried everything imaginable regarding the username and password for the task. It makes no difference. When I run the CFM page in my browser, the page works correctly and generates an email just like it should. I just can't make it run as a scheduled event.
Is the scheduled task folder has any check for the session or anything? I mean is the scheduled task folder is accessible without login? Please try with removing all the redirect rules for the application. That might work.
For me the requests were timing out. I increased the timeout in the administrator and that solved it. Doing a cfhttp in a test file and dumping the results helped me troubleshoot it.
