Power BI support is still Preview, and this 401 is coming from the DAX execution call rather than sign-in.

Can you confirm the following for what you are trying to access ?

1. The semantic model has to sit on Premium, Fabric or Embedded capacity. DBCode uses the Arrow Execute DAX Queries API and that one is capacity-only, so a Pro workspace on shared capacity will list fine and then fail here. A Fabric trial capacity is enough to test with.
2. A Power BI or Fabric admin needs "Dataset Execute Queries REST API" enabled under Tenant settings, Integration settings, along with "Allow XMLA endpoints and Analyze in Excel with on-premises semantic models".
3. Your account needs both Read and Build on the semantic model. Read alone is enough to see it in the list but not to query it.

Full list is at https://dbcode.io/docs/supported-databases/powerbi if you want to check them off.

If all three are already in place, let me know which sign-in option you picked (Editor sign-in, Default credentials, or an auth profile) and whether the workspace lives in your own tenant or one you're a guest in. There's no tenant picker on the connection yet, so guest access to another tenant won't work at the moment.
