Subject: 3D viewer does not work

Since this morning, the 3D viewer does not work.
when I clic on 3D, the green windows is displayed with adress :
http://files.sokker.org/matchviewer/matchviewer3d.html
loading match data
0% match data, and nothing else, no data is loaded

i use Firefox 51.0b14 (32 bits)

2d works OK

Must be a problem on Your side...everything works fine with me, the 3D works, I just watched a NT game

on a new Firefox session, the first time I launch the viewer 3D it needs more than 2 minutes to run the match.
after in the same session, it is ok. so I search why?
I 'm happy to see that it is not a flash problem.
