This solution applies to any Barracuda Networks product with a DNS misconfiguration.
It is normal for the Energize Updates and the Firmware Update pages to take longer to load because the Barracuda unit must contact our update servers to supply the most current versions of updates available. However, if the Firmware Update page won't load or the Energize Updates give an error code -9, the problem is very likely related to the your DNS configuration (or your DNS server itself). Check your DNS settings, and if you are confident they are correct, please upgrade your firmware to the latest available version. If you are unable, or if this does not resolve your issue, please call Barracuda Networks Technical Support for assistance.
