Cause

This can happen when the tasks in the Monitoring screen could not be found in the archive.
And when you navigate to Monitoring > deployment tasks in the Deploy GUI, you can see tasks in the state below.

Steps to Follow

From the screenshot, We can see that the task cannot be found in the archive, which means the task might have been archived or the task file is removed from the work directory. Check if you have any scripts that clean the work directory every time?

Also, please try to locate Task ID 15778a2bxxxxxx-xxx-xxxxx-xx in any of these tables:

• XLD_ACTIVE_TASKS
• XLD_PENDING_TASKS
• XLD_ARCHIVED_UNKNOWN_TASKS

If the Task is nowhere to be found, the related error in the log should not be present after a restart. If the task is in the table, please do try to remove the task and restart the Deploy.
