This type of error is generally network related. While this Communities Discussion talks about network communications to a VIP for a cluster configuration, the content still applies with respect to network communications.
According to the agentparm configuration you use port 3521 for agent and scheduler port communications.
As this error is typically network related, confirm that port 3521 is opened bi-directionally on your firewall.
