Sometimes, while using the GFI LanGuard Agent Diagnostics tool, it indicates that the agent fails to communicate on port 1072. This article describes the possible root causes and resolution of this issue.
The error above indicates that the agent is unable to communicate with the server. There are multiple possible reasons for such a situation:
- A firewall might be blocking the required ports - refer to the Firewall Ports and Permissions sections of the Required Settings to Scan a Machine and Successfully Install Missing Patches Using GFI LanGuard article for the details.
- The communication server (Apache) on the GFI LanGuard server might be down. In such a scenario the GFI LanGuard console would display the message Communication server not running. If this is the case, follow the diagnosis and solution steps from the corresponding article.
- There might be names resolving and network connectivity problems - Verify Required Network Connectivity and Security Permissions for GFI LanGuard Operations.
If the most common root causes diagnosis revealed no issues, to resolve the error perform the following steps:
- Ensure the system is presenting the correct IP address and port for communicating with the agents:
- Launch GFI LanGuard console and go to Configuration > Agents Management > Agents Settings.
- If the Address is set to
Default, change it to the actual server IP address.
- Check the TCP port, which is 1072 (for LanGuard 11 - 1070). Make sure your firewall allows inbound connections
Ensure that the GFI LanGuard server and the client computer have enough free disk space on the C drive.
If you are using the WSUS server for the patch repository ensure that the UNC path is being used, check this under Configuration > Patch Auto-download > Patch Repository.
Run the GFI LanGuard Agent Diagnostics tool and verify that the error is no longer displayed. If the issue persists, contact the Support Team.
