So almost 4 years later we had to reinstall the whole Cloudron VM and we were depending on the backups Cloudron made.
Since it was (by mistake) the only thing we had left at this point.
So we powered down the VM and did the restore process.
It had a lot of data to restore, but the dashboard was back up and running smoothly in just 20 minutes.
So BIG Thanks to the Cloudron team for such a stable and good working product 🥳
