I would suggest to try a firmware install from CLI:
- Perform the following Expert Mode command in order to allow SCP protocol connection:
bashUser on
- Please download the latest GA version offirmware for your appliance
- Enter the appliance via WinSCP connection of SCP protocol and upload to the /storage directory the latest GA version image.
- Before uploading image to /storage directory, all the files in this directory have to be deleted.
- Perform the following Expert Mode command for a manual upgrade via CLI:
upgrade_revert_image.sh /storage/%FILENAME% upgrade safe
