Thank you for taking time for me.
The problem exists with any adress (even my own website)

I am trying with this one, for example :

<iframe src=”https://www.geogebra.org/material/iframe/id/zpJS9C7a/width/700/height/500/border/888888/smb/true/stb/false/stbh/false/ai/false/asb/false/sri/true/rc/false/ld/false/sdz/true/ctl/false”></iframe&gt;

It works outside the spoiler code, but not inside.
