Power BI dataset refresh error — what it means and how to fix it.
What this means
An OAuth2 token expires roughly 1 hour into a long refresh and the gateway cannot auto-renew it.
How to fix it
- Shorten the refresh to under 1 hour (use incremental refresh).
- Re-enter the OAuth credentials.
- Split large loads so no single refresh runs past the token lifetime.
