If able to login to DPC via admin/root successfully , then proceed below.

2. Check logs on ACM

/usr/local/dataprotection/var/configmgr/server_data/logs/server.log:

//Search for below string to see when and how many times DPC root password has gone out of sync:

#grep -i "Setting dpcRootPasswordOutOfSync=true" server.log*

server.log.18:2020-09-22 16:10:26,459 INFO [Thread-3200180]-dpcadapter.DPCUtil: DPC root password is out of sync, throwing exception
server.log.18:2020-09-22 16:10:26,459 INFO [Thread-3200180]-dpcadapter.DPCUtil: Setting dpcRootPasswordOutOfSync=true

Cause

Cause : When DPC becomes slow to respond (maybe due to some jobs / activities) the command fired for checking the password sync does not get the prompt in expected time (which causes command execution timeout) which results in failing scenarios.

Resolution

Resolution : Engineering has fixed this Issue in IDPA 2.7.0 code.
