# Troubleshooting

***

#### Q: When exporting data to Power BI from multiple Jira instances, one connects fine but another returns an error upon attempting to connect. What might be the problem?

**A**: Initially, ensure you're utilizing distinct API tokens for each Jira Instance and entering the correct email addresses for authentication in Power BI. If the error persists before even reaching the authentication stage, it may be necessary to reset permissions and establish new connections from scratch. For comprehensive guidance on how to accomplish this, please visit our [**dedicated Tips and Tricks page**](https://thecode4.gitbook.io/thecode4-docs/user-guide/tips-and-tricks-for-effortless-and-fluent-work-with-bi-tools/how-to-edit-or-clear-permissions-for-an-existing-data-source-connection-in-power-bi-desktop).

#### Q: Why is my Power BI report showing outdated data?

**A**: Outdated data in your Power BI reports, coupled with reduced performance, is likely due to accumulated cache files. Clearing the cache should resolve this issue. For detailed instructions on how to clear the cache, please refer to our [**dedicated Tips and Tricks page**](https://thecode4.gitbook.io/thecode4-docs/user-guide/tips-and-tricks-for-effortless-and-fluent-work-with-bi-tools/how-to-clear-the-cache-in-power-bi-desktop).

#### Q: Error 510: Why can't I refresh data in Power BI/Tableau/Looker Studio, or why are the CSV/JSON/Excel/PDF files empty after export?

**A**: Users may experience this error if they have included fields in their data source that are exclusive to the paid versions of the Data Processor app, identified by 'stars' signs (e.g., <img src="https://3783386375-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FWbAZwNh39hWp69xdDNc6%2Fuploads%2FHX8ukHQ0eKZy0T5gCaai%2Fpro_stars.png?alt=media&#x26;token=e00ed902-83ff-4260-ac13-3c3060dd66f5" alt="" data-size="line">**Available only for PRO version** or <img src="https://3783386375-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FWbAZwNh39hWp69xdDNc6%2Fuploads%2FbcVLfli3L1AOfB014UAK%2Fxray_stars.png?alt=media&#x26;token=853e905b-3e58-4c83-bf8c-1a1d29e32e69" alt="" data-size="line">**Available only for Data Processor for Xray**). This problem usually arises if the license for these paid add-ons has expired or if such a plugin has been uninstalled from your Jira instance.<br>
