Custom widget: Network error for loading resource for the CUSTOM widget

Dear all,

I have built a very simple widget, have a web hosting space and loaded the JS onto a web space folder.

When using a normal browser and open the link ("override URL"+"files"), I can see the JS code.

When opening the widget on the same browser session in Workspaces, I get an error message "Could not load the following additional widget resources: CUSTOM widget - Javascript"

Any ideas from anybody where I go wrong or what I am missing?

Thanks

:-)
