ERROR: The request could not be satisfied.
If you are trying to export one of your dashboards as a PDF and get an error message like the above, the issue stems from the report timing out.
Generating a report with multiple bar charts with value labels will increase the load time and result in the time out error. Once the value labels are removed, you should be able to download a PDF of the dashboard without any issues.
If this continues to be an issue, you can try improving query performance by limiting queries or separating charts into multiple dashboards to reduce the size and activity on the dashboard. Please take a look at the support documentation on Improving Query Performance for more information.
