Summary

You may notice the following heartbeat error in the Deep Security Manager console:

Event ID: 4011
Event: Failure to Contact Manager

Details
Public

There are several reasons why this heartbeat error occurs. Below are some possible causes and their respective solutions:

Scenario 1. Error is caused by refused connection

The following description appears:

Level: Warning  Event ID: 4011  Event: Failure to Contact Manager  Description: Unable to contact Deep Security Manager at URL=dsm://dsmip:4120/ with IP=10.50.100.232 due to the following error: Connection refused

In such situation, Deep Security Agent (DSA) proactively rejects DSM's heartbeat. Do the procedure below to resolve the issue:

  1. Double-check the following configuration:
    • DSA should still be managed by this DSM.
    • There should be no permission issue in the local DSA.
    • Port 4118 (for DSA) and port 4120 (for DSM) should be open.
  2. Reset and reactivate the DSA.

Scenario 2. Error is caused by connection timeout

The following description appears:

Level: Warning  Event ID: 4011  Event: Failure to Contact Manager  Description: Unable to contact Deep Security Manager at URL=dsm://dsmip:4120/ with IP=10.50.100.232 due to the following error: Connection Time Out

In this scenario, DSM sent a heartbeat request, but failed to receive a reply within the alloted time.

To resolve the issue:

  1. Make sure the network connectivity is working fine.
  2. Re-try sending a heartbeat.
