CCR replication StorageSummaryStatus service down on primary mailbox server

replication seem to be fine on the passive node, logs has been trimmed. copystatus is healthy on passive node.  However, on the primary node, I see servicedown for the storagecopystatus.  I believe this happens after previously implemented dpm for backup and reseed from the passive node. Am I missing anything? please advise,
