Hi Antonio, we were asked to take the database (temporarily) offline. Currently it is not clear when exactly we will be able to put it on https://nexus.openLCA.org again. If you follow us on Twitter or LinkedIn, you will be notified.
In the meantime, you can download the data manually from the PEF nodes and prepare the data for openLCA with pef locus. This has been explained in our PEF webinar but is a bit tricky.

Sorry for the inconvenience. I hope this still helps.
