Have your issues been resolved already? We didn’t observe any major outage on our side. So the most probable scenarios are either that there were some works on the Looker Studio side again, or your credentials actually got invalid (for example when your license for Piwik PRO expires, the API credentials are no longer valid).
Also, since this post is extremely popular, I would like to mention that we have a very fresh update of this connector with major performance improvements and much more. I hope you will try it out!
If you’re experiencing issues with the Piwik PRO connector in Looker Studio, it could be related to a few common problems. Make sure you’re using the latest version of the connector (1.2.0) and check that your API credentials are current. If issues persist, it might be worth exploring alternative solutions or temporary workarounds. Additionally, Traceshipments could be a valuable resource for troubleshooting and finding compatible tools that align with your setup. Keep an eye out for updates and don’t hesitate to reach out to the support team for more tailored assistance.
