Depending on the interval you have set for that task on the Company Automation page, it may have already run via cron. You can check the timestamp next to the task on the Company Automation page for "Download Tickets" to see if it has ran in the last few minutes. Assuming you have a 5 minute interval on that task, if the timestamp next to the task is not within the last 5 minutes, it did not complete.
Tasks can't be forced to run outside of their scheduled interval, so running the cron manually may not run the task. Adding to what I mentioned in the previous thread I linked, you would need to set a `log_cron`.`end_date` in the database that is more than 5 minutes from now, and then immediately run the cron manually through the interface. If the task fails to run again due to some error, you'll see that error in the interface when running the cron manually.
