Schedule Refresh stopped working and this error occured

This error is coming from the gateway. Go to the gateway and update the OAuth connection to a service account. You might be using a users account and password and that expired.

Aso, if you are using a service provider, then you have to code a mechanism to refresh the token every hour.

Hi, Nbz78 

Thanks for the reply from Anonymous , please allow me to add to it:

The error message you're encountering might be related to expired or invalid credentials stored in the Power BI service. Navigate to the dataset settings in the Power BI service and verify that the credentials are still valid under the Data source credentials section. If they've expired or changed, you may need to re-enter them. For more details on managing data source credentials, see the following documents:

If the data source requires a gateway to refresh, make sure the gateway is online and up to date. Sometimes, stale or offline gateways can cause refresh issues.

Review the refresh history, which provides a deeper understanding of what might be causing a refresh to fail.

Sometimes, clearing your internet browser cache can fix unexpected issues. After the cache is cleared, sign in to Power BI again and try to configure scheduled refresh.
