How to troubleshoot HTTP communication failure

This page provides the steps to troubleshoot HTTP communication failures in DataSecurity Plus.

Symptoms of error due to HTTP communication failure

The DataSecurity Plus agent audits Windows file servers, failover clusters, workgroup servers, and workstations in real time, and forwards collected event data to the DataSecurity Plus server through the configured HTTP(S) port.

  • To learn more about the default HTTP(s) port used by DataSecurity Plus, refer to the Port configuration guide.
  • To learn more about the DataSecurity Plus agent, refer to the Agent document.

Issues in this agent-server communication path will cause the "No HTTP Communication available for more than 24 hours" error message to show on the product console under [Configured module] → Configuration → [Source] → Manage Agent.

At the end of the Manage Agent page, you'll find the below information:
Last HTTP Communication Time : -
Last Attempt Time : - [Failure]

Causes of HTTP communication failure.

Two common reasons for getting the "No HTTP Communication for more than 24 hours" error:

  • The agent is unable to forward data to the DataSecurity Plus server.
  • Agent properties do not match the corresponding server properties.

Steps to resolve the HTTP communication error.

  • Check if the agent is able to forward event data to the DataSecurity Plus server.

    • Log in to the machine where the agent is installed. Connect to the DataSecurity Plus server through a web browser (we recommend using Internet Explorer or Edge) by typing Protocol>://<Server Name>:<Port number being used>.
    • If this test fails, check the inbound and outbound firewall setting on the target computer and the DataSecurity Plus server, and open the port being used by DataSecurity Plus.
  • Check if the agent properties match the corresponding server properties.

    After executing step one, click on the refresh icon at the top right of the Agent Property table under [Configured module] → Configuration → [Source] → Manage Agent. Check if the status of every entry is marked with a green check.

    • If the properties do not match, log in to the machine where the agent is installed that has the property mismatch. Open Run, type regedit, and click OK. Navigate to HKLM → Software → ManageEngine → FAP, and update the values of the entries with the corresponding values in the IN SERVER column of the Agent Property table.
    • If you are unable to refresh the Agent Property table, check if the Remote Registry Service is running on the machine where the agent is installed. If it's not running already, start the service.
    • Refresh the Configuration Sync Details table on the Manage Agent page to ensure that all recent changes are updated.
