NWA130BE won't update from firmware version V7.20(ACIL.3) to V7.30(ACIL.2)

Hi @sernek,

I understand you're experiencing an issue updating one of your Nebula-managed NWA130BE access points from firmware V7.20(ACIL.3) to V7.30(ACIL.2), while your other NWA130BE updated successfully. This can be frustrating, but we can troubleshoot it.

Here are some steps you can take to address this:

• Check DNS Resolution: Firmware update failures can often be related to DNS issues. Ensure your NWA130BE can properly resolve the Zyxel firmware download servers. You might try configuring your DNS server to 8.8.8.8 on the AP's local GUI if possible.
• Verify Firewall Settings: Confirm that your network's firewall is not blocking the necessary ports for Nebula device management services and firmware downloads. Detailed port information can be found on the Zyxel Nebula firewall information page. The firmware update domain that needs to be accessible is firmware.nebula.zyxel.com on port 443.
• Ensure Stable Internet Connection: A stable internet connection is crucial for downloading firmware updates.
• Try Alternative Update Methods: If updating through the Nebula Control Center continues to fail, you can attempt to update the firmware via FTP or the ZON utility. Instructions for these methods are available in the Zyxel Community.
• Check for "Locked" Status: In some cases, if an AP's firmware availability shows a "Locked" status, it may indicate issues with past upgrades or specific site configurations. If you encounter this, contacting Zyxel Nebula support is recommended to unlock the firmware status.

To help us investigate further and provide more specific guidance, please provide the following information:

• Device model: NWA130BE (already provided)
• Current firmware version: V7.20(ACIL.3) (already provided)
• Network topology map: A diagram illustrating how your NWA130BEs are connected to your network.
• Error message screenshots: Any error messages or logs you observe during the failed update process.
• Enable Zyxel Support Access: Please enable Zyxel Support Access via Help > Support Request in the Nebula console. This action authorizes the Zyxel support team to directly view your cloud environment configuration, significantly shortening troubleshooting time.
• Organization or Site name: Please provide the name of your Nebula Organization and Site.
