Troubleshooting
Problem
In IBM Security QRadar V7.2.6, you can't log in to the Qradar Console from a computer that is within the 172.17.0.0/16 IP address range.
Symptom
If you log in to the QRadar Console by using SSH or the web, access to the QRadar Console is denied from computers that are within the 172.17.0.0/16 IP address range.
Cause
The 172.17.0.0/16 IP address range is the default range that is used by Docker as a part of the QRadar App Framework.
Resolving The Problem
To resolve the issue, try one of these workarounds:
- If possible, don't log in to a QRadar Console V7.2.6 from computers that are within the 172.17.0.0/16 IP address range.
- If you do not use apps, you can temporarily disable the Docker process that QRadar uses. To disable the Docker process, follow these steps:
- Open a terminal and use SSH to log in to your QRadar console from an IP address that is outside the 172.17.0.0/16 address range.
- Enter the following commands:
- If you are using apps in QRadar or must connect from machines within the 172.17.0.0/16 IP address range, contact QRadar support for help to change the default IP range that Docker uses.
Where do you find more information?
- /opt/qradar/init/qdocker -m stop

The Docker process is restarted when the QRadar disk maintenance processes are next run.
