Energy analysis for Dynamo doesn't work

Hello everyone, I’m working on a thesis about energy optimization in a BIM environment using Revit and Dynamo, and I’ve been asked to use only Autodesk software. To use Green Building Studio, I installed the Energy Analysis for Dynamo package and followed the only tutorials on YouTube that I found, but despite the nodes seeming to be correctly set up, it doesn’t allow me to perform the analysis because it seems unable to connect to GBS. (I have a student license) I’ve already read all the previous discussions on the topic and wanted to know if anyone had actually managed to use it and if they know what the problem might be. Thanks in advance for the help.
