Cannot Connect to Semantic Model

I've modelled and published a data model to my power BI account

However, when I try to use the semantic model as a data source for a new report, I get this error message:

At first, I tought this had to do with connection settings as the model connects to databases in SQL Server and ElasticSearch. However, after setting up the gateway I still got the error.

I then made a test with a second data model, with a simple excel file, and got the same error when trying to connect to it.

I'm using the same company account. In previous jobs I had successfully built this process without errors.

Is there any additional setting I need to configure in order to connect?
