BIRT Reporting Font issue from Webportal

Hello,

I have a workflow in Knime 4.7.7 that creates a report. When I run it locally, the PowerPoint report is correctly visualized.

However, when I run it from the web portal, all the fonts in the PowerPoint are converted into Times.

I already asked the admin of the KNIME server to install the fonts I need, but this did not solve the issue. Any idea of what could be the source of the issue?

I am adding the workflow I used to create these snapshots.

PPT_Report.knwf

Thank you in advance.

Best,

Ste
