Troubleshooting: Couldn't upload new firmware
New firmware doesn't upload if the file is incompatible or corrupt, or if the hardware doesn't have the standard configuration.
Wrong or incompatible firmware image.
You're uploading a firmware image that's incompatible with the active version. For compatible versions, go to Sophos Licensing Portal and see the versions listed for the device.
Incorrect firmware image or appliance hardware.
The appliance (hardware, virtual, or software) hardware configuration doesn't meet the firmware requirements.
Use a different firmware version. Alternatively, download the firmware image from Sophos Licensing Portal and move Sophos Firewall to it.
