On November 9, 2026, Microsoft released an important update for the Microsoft Entra Private Network Connector. The Entra Private Network Connector is used to publish on-premises web applications to the internet. It is also used for Global Secure Access (GSA) with Entra Private Access, allowing GSA clients to access on-premises resources. Entra Private Network Connector v1.5.5130.0 includes new functionality to improve performance monitoring, name resolution, logging, and overall reliability and security.
New Features
This release introduces new capabilities for monitoring connector performance and resolving names in complex network environments, including the following.
Performance and Diagnostics
The Connector Diagnostics tool, available from the system tray, now includes a new Performance tab. Here, administrators can view up to 24 hours of resource history for the connector server, collected in one-minute aggregates. The Performance tab displays average and peak values for the following metrics.
- Machine CPU: Total CPU usage across the machine.
- Connector CPU: Share of total machine CPU used by the connector.
- Connector resident memory: Physical memory used by the connector process.
- Machine available memory: Physical memory still available to applications.
Administrators can use the Window drop-down list to display performance history for the last 1 hour, 6 hours, or 24 hours. This gives better visibility into resource consumption over time, which is helpful when sizing connector servers or investigating performance issues. In addition, this update improves the accuracy of connector health reporting.
DNS Resolution
The connector now honors DNS suffixes and DNS servers configured on individual network interfaces in Windows. This update also improves the fallback behavior for DNS SRV record queries.
Improvements
In addition to new features, v1.5.5130.0 includes several improvements to logging, reliability, and security.
Logging and Observability
This update includes the following changes to connector logging.
- Trace file rotation is now supported.
- The default capacity for the Session event log has been increased to 3 GB.
- Error messages for connectivity and backend failures have been improved to streamline troubleshooting.
Note: With the larger default Session event log size, administrators should ensure the connector server has sufficient free disk space on the system drive.
Reliability and Security
This update also includes the following reliability and security enhancements.
- TCP keepalive has been added to reduce idle connection resets.
- Memory management during request processing has been improved.
- Security for local log files and other connector files has been enhanced.
Updating to v1.5.5130.0
Existing Entra Private Network Connector installations will not automatically receive this update. Administrators must manually download the connector from the Microsoft Entra admin center and apply the update themselves to take advantage of these new features and capabilities.
