The root cause of the issue is that the time difference between Data Domain and PPDM is too large. In this case, the time on Data Domain is 15 minutes ahead of the time on PPDM. The connectionDescription is set to a negative value "-1383149567" due to this time difference, causing the ddp_disconnect.
Configure NTP on both Data Domain and PPDM server to synchronize the time. Rerun the backup with Retention Lock Mode enabled.
