You see informational events with the following errors in the BoxMonitor logs on a Data Loss Prevention detection server:
INFO: Operation com.vontu.communication.transport.AcceptWrapperOperation:1607800648768:null:com.vontu.communication.transport.SessionIdentifier@6e50417e failed with exception: com.vontu.communication.transport.exception.TransportException: invalid packet length on read: 369296131
External service Health Checks, such as from a load balancer, are directed at the detection server to see if port 8100 is open.
Endpoint Agents have been deployed with port 8100 specified instead of port 10443.
No action required.
Re-deploy agent packages with the correct port specified. The default port is 10443 - be sure to specify the port you have configured the detection server to listen for agents on.
