WebGL Lighting Issue

I’m attempting to upload my game to Itch.io using Web.Gl. After I finished uploading, I found out my game looks like this in the browser.

For reference, the game is supposed to look like this. This photo was taken in the version exported to my Mac locally.

It seems like the main platform (White rectangle) isn’t being lit up. This could either be because of the fog i’m using, or a lighting bug. Both of the versions (WebGL and Mac) were exported under the same project/player settings, so I don’t know where this issue originates from.

I’m very new to Unity, and any help is appreciated. Thanks!

Do u have solved it? I’m having the same problem!
