There is VPS migration task in Services > Cloud Infrastructure > Migration Tasks stuck in Running state: it is not possible to cancel or delete it. The following error is shown:
Deleting of migration task has failed. Reason: task has the Running status.
Most likely there is a cancelled/unprocessed task in Task Manager
Please check cancelled/unprocessed tasks by filtering them using vps_operations_ID queue where ID is the ID of the VPS. If the task is failed, check the reason of the failure, fix it and re-run the task. If there is no such tasks or the task was cancelled and then rotated, then it will be necessary to apply DB modifications. Please contact Parallels technical support in such case.
