If it's been disabled automatically after some time (15 min) then it's an issue with the Lingering Objects, you have to check the event viewer for the Event ID 1988.
If your environment configured with Strict Replication Consistency, then the Inbound replication of the directory partition of the lingering object has been blocked on the destination domain controller.
You have to remove the Lingering Objects to resolve this issue.
