Hello Hugo,
To provide more info regarding the issue you are experiencing, could you please download the logs from the Shake (instructions can be found here, if needed: Please read before posting!) and post them here? This is to cover our bases on all sides.
As you are operating via SSH, you can also find them in /opt/log/; you can download all files, zip them, and then attach the zipped file to your answer.
Thank you!
