PAM or Operating System level restrictions can cause this issue.
Possible Reasons:
1. Check If Privileged Access Manager is enabled then PAM admin should help
2. Check if Operating System is hardened then check with Unix Admin.
3. Check if the user Account is locked, unlock the account and try.
Ensure that below commands work before failover
ssh-copy-id -i dradmin@target_host
ssh dradmin@localhost
