OFFICIAL Game Not loading/WebGL disabled/frequent crashes

[uma437]

Hi,
I cannot load the game in any browser (edge, chrome,opera). The screen stays black.

If I test these suggestions:
"1.WebGl Support: https://get.webgl.org/
If you see a rotating cube, your browser supports WebGL.

2.Simple WebGL/WebAssembly project:
https://w3.slashkey.com/flash/farm/m...ets/index.html
You should see a blue sky with a couple of icons.

3.Unity WebGL/WebAssembly tank demo game:
https://files.unity3d.com/marcot/tan...736.1609800030
You should see small tanks and buildings in the desert.

4.FarmTown game with demo farms and no compression/caching (slow to load, please be patient):
https://w3.slashkey.com/flash/farm/m...oDC/index.html "

I get these results:
1. works in all browsers. 3 also in opera. 2 and 4 stay black in opera, 2-4 show a 404 page in chrome and edge.

Any idea what I can do about that?

Thanks for helping!
Ursula
