Work through the sections below based on where the error occurs. ## Refresh errors in Power BI Desktop ### "The credentials provided are invalid" or authentication errors Your Tugger report credentials may have changed or been entered incorrectly. 1. In Power BI Desktop, go to **File** > **Options and Settings** > **Data source settings** 2. Find the Tugger OData entry in the list 3. Click **Edit Permissions**, then click **Edit** under Credentials 4. Select **Basic** on the left 5. Re-enter your **Username** and **Password** from Tugger's Report Setup page (use the copy buttons to avoid errors) 6. Click **Save**, then try refreshing again If you've recently regenerated your credentials in Tugger, you'll need to update them here. See [Regenerating Report Credentials](/docs/regenerating-report-credentials). ### "Unable to connect" or timeout errors Power BI can't reach the Tugger data service. - Check your internet connection - Check whether your company firewall or VPN is blocking outbound connections to `*.tuggerapp.com` - Try again in a few minutes. Occasional connectivity issues can be temporary ### "The OData feed URL has changed" or URL mismatch The OData URL in your report doesn't match the current URL in Tugger. 1. In Power BI Desktop, go to **Home** > **Transform data** > **Edit parameters** 2. Compare the OData URL with the one on your connector's Report Setup page in Tugger 3. If they differ, update the URL in Power BI, click **OK**, then refresh ### "Access to the resource is forbidden" This usually means the credentials are valid but don't have access to the requested data. - Check you're using the credentials for the correct connector (each connector has its own username and password) - If you have multiple connectors, make sure the OData URL and credentials are from the same connector ### Data source settings are corrupted If refresh keeps failing and none of the above helps, clearing and re-entering your credentials can fix corrupted settings. 1. In Power BI Desktop, go to **File** > **Options and Settings** > **Data source settings** 2. Find the Tugger OData entry and click **Clear Permissions** 3. Click **Delete** to remove the entry entirely 4. Close the dialogue 5. Click **Refresh** in the Home ribbon 6. Power BI will prompt you to enter credentials fresh. Select **Basic**, enter your Username and Password, and make sure the dropdown matches the Tugger URL ## Refresh errors in Power BI Service (online) ### Scheduled refresh fails If your scheduled refresh is failing in Power BI Service: 1. Go to [Power BI Service](https://app.powerbi.com) 2. Open your Workspace and find the **dataset** (not the report) 3. Click the **Settings** icon (gear) or hover over the dataset and click **Schedule refresh** 4. Under **Data source credentials**, click **Edit credentials** 5. Set the authentication method to **Basic** 6. Re-enter your Tugger **Username** and **Password** 7. Click **Sign in** Common causes of scheduled refresh failures: - Credentials have been regenerated in Tugger but not updated in Power BI Service - The authentication method is set to something other than Basic (e.g. Anonymous or OAuth) - The gateway connection settings are incorrect ### "You need a gateway" message Tugger's OData feed is a cloud data source and should not require a gateway. If Power BI Service asks for one: - Check that the OData URL starts with `https://` and matches the URL from Tugger's Report Setup page - Make sure the data source credentials are set to **Basic** authentication, not Windows or other types - If the issue persists, try removing and re-adding the credentials in the dataset settings ### Manual refresh works but scheduled refresh fails If you can manually refresh the dataset but the scheduled refresh fails: - Check the refresh schedule is actually turned on (it's off by default) - Make sure the refresh time doesn't conflict with your Tugger sync schedule. If your Tugger sync runs at 08:00 UK time, schedule Power BI to refresh at 09:00 or later - Check the refresh history for specific error messages: go to the dataset settings and look for **Refresh history** ## Checking refresh history Power BI Service keeps a log of refresh attempts: 1. In your Workspace, click on the dataset 2. Click **Refresh history** (or find it in the dataset settings) 3. Review the status and error details for recent refreshes This can help pinpoint whether the issue is with credentials, connectivity, or something else. ## Still having trouble? - Make sure Power BI Desktop is updated to the latest version - Try opening a fresh copy of the report template from Tugger and entering your credentials from scratch - [Contact the Tugger team](https://tuggerapp.com/Contact) with details of the error message and we'll help you get it resolved --- **Related articles:** - [Connecting Power BI Desktop to Tugger](/docs/connecting-power-bi-desktop-to-tugger) - [Publishing to Power BI Service](/docs/publishing-to-power-bi-service) - [Regenerating Report Credentials](/docs/regenerating-report-credentials)
