Hi...
My application works offline correctly, but when i upload to my hosting, it won't start, it keeps on the Loading screen.
WASM file is about 20mb so it should load in 5 seconds approx.

I think i have uploaded all needed files... not sure..
I'm using Qt Quick Qt 6.9.0

Thanks in advance.

Edit:
Added the console bowser:

Have you set the mime type as instructed by the error log?

my knowledge is very poor in web development, can you point me how to reach that?..

Thanks.

Edit:
I managed to add application/wasm with .wasm extension in CPanel, so then, tried again, and i got this:

I don't know, sorry.

If I remember well, this SharedArrayBuffer is needed when using wasm multithreading.
If your app does not need multithreading, use Qt wasm single threading.
If multithreading is needed, check https://forum.qt.io/post/765010
