Streaming oplog: no starting point defined

We have mongodb community 6.0 server and PBM 2.4.1.

PITR is enabled every 10 minutes.

During backup we got error:

PITR incremental backup:

========================

Status [ON]

! ERROR while running PITR backup: 2025-11-02T20:33:08.000+0300 E [rs0/rc-mongo-gridfs-2:27017] [pitr] streaming oplog: no starting point defined; 2025-11-02T20:33:06.000+0300 E [cfg/rc-mongo-gridfs-config-3:27019] [pitr] streaming oplog: no starting point defined

2025-10-31T21:00:02Z 15.40TB <logical> \[restore_to_time: 2025-11-02T11:20:04Z\]

There is no any pitr directories after 2025-10-31T21:00:02Z after last full backup started.

How can we fix it?

Hi @Magzhanova, Could you please share the latest PITR execution logs so we can see if any additional errors are present?
