My excel dashboard is no longer showing the reports from ReportBuilder used to obtain the data. The data itself is still there but the reports are not. There were about 20 reports in this dashboard. Is there a way to recover the Report Builder reports so I do not have to rebuild this entire dashboard?!

I'm unable to open Report Builder in my Excel files using my usual company logo. I'm able to access the web app just fine with the same credentials. I have uninstalled the old report builder, and reinstalled the latest but still receive the same error. Any ideas on what's going on at this point? See error attached.
