usg flex h new firmware 1.37

Hi @MassimoRiva,

I understand you're experiencing issues with some services after updating your USG FLEX H series devices in an HA Pro configuration to firmware 1.37.

When updating firmware on USG FLEX H series devices in an HA configuration, it's crucial that both devices are running the same firmware version. If there's a firmware mismatch, the HA pairing will show an error. The USG FLEX H series also has a configuration rollback feature for firmware versions 1.30 and above, which reverts to the previous working configuration if the new configuration fails to apply.

To help us investigate this issue further, please provide the following information:

• Device Models: Please specify the exact models of your USG FLEX H series devices.
• Current Firmware Version: Confirm that both devices are currently running firmware version 1.37.
• Detailed Problem Description: What specific services are experiencing problems? Can you describe the symptoms you are observing?
• Network Topology: A diagram or description of your HA Pro setup, including how the devices are connected and the heartbeat port used.
• Error Messages: Any error messages displayed on the device dashboard or in the event logs.
• HA Status: The current HA status from System > Device HA > HA Status on the primary device.
• Diagnostic Logs: If possible, please download the diagnostic logs from both devices by navigating to Maintenance > Diagnostics > Diagnostics in the web GUI and clicking "collect now."

Additionally, if your devices are managed by Nebula, please enable Zyxel Support Access:

• Go to Help > Support Request in the Nebula console.
• Provide your Organization and Site name.

Enabling Zyxel Support Access allows our support team to directly view your cloud environment configuration, which can significantly expedite the troubleshooting process.
