QRadar: Autoupdate and name resolution



If name resolution is not working, the auto update cannot connect to download updates.


When an auto update fails to connect and install an update the following system notification is generated for QID 38750066:

38750066 - Automatic updates could not complete installation. See the Auto Update Log for details.

Diagnosing The Problem

The logs can display connection issues or DNS query issues in the logs for administrators. If name resolution fails for any reason when the auto update is run, a system notification is generated and an error message is displayed in the auto update logs.
  1. Log in to the QRadar Console as an administrator.
  2. Click the Admin tab.
  3. Click Auto Update icon.
  4. Click View Log to verify the Last Update Status.
  5. If the log displays an error for name resolution, the auto update cannot complete.
    Could not contact the update server: 500 Can't connect to 
    (getaddrinfo: Temporary failure in name resolution)
    Could not download manifest list.

Resolving The Problem

For auto update to work, the auto update server address and proxy server address, must be resolved. If the problem is caused by a temporary problem with your DNS server, ensure that your DNS server is functional and available on the network. If you suspect your DNS configuration is incorrect, it must be corrected. For more information on how to configure DNS for QRadar 7.3.x appliances, see How to change the DNS IP address entries with the command-line interface for QRadar version 7.3.0.
