MMM-TomTomTrafficIncidents display issue on PI zero

[splaliv845]

Hi,
I am new to this. First thanks to the community, your work is fantastic.
Just made my mirror, I will share some picts soon.

For integration purpose I choose to run MagicMirror on a pi4 that stay with all my house IT systems.
The mirror itself run a pi zero in a kiosk mode.

So, for all my modules are working (weather, air pollution, time zone, news and train info).
MMM-TomTomTrafficIncidents is working well if I display the dashboard on my computer with Chrome or even directly on the PI4.
However, the PI zero doesn’t load the picture of the traffic.
I can only see the TomTom copyright.

I was wondering if someone could drive me to some direction?
I don’t think it is coming from MagicMirror configuration or the module.
Rather PI Zero and the Kiosk, web browser…

thanks.
Ju.
