Might be a DB replication issue.
Issue this command on the CLI from your publisher:
admin:show perf query class "Number of Replicates Created and State of Replication"
The value of Replicate_State should be 2.
0 - Replication Not Started. Either no subscribers exist, or the Database Layer Monitor service is not running and has not been running since the subscriber was installed.
1 - Replicates have been created, but their count is incorrect.
2 - Replication is good.
3 - Replication is bad in the cluster.
4 - Replication setup did not succeed.
