Drawio progess bar still continue

[cdelayre]

Hi

I deployed Drawio in a standalone Tomcat container. I tried to use drawio-editor extension changing all reference in the code to https://www.draw.io to my local instance. In a wiki page, I put the wikicode {{#drawio:ChartName}}. The Drawio webapp correctly appears in an iframe when I edit the diagram. But the loading progress bar still continues and never ends. I can only access to menu items "File/Quit" and "Help".

Any idea of what's going on?

Thanks
