Question WebGL doesn't load

Asked this in the wrong place.

I'm trying a Web build for the first time ever. The build launches in Firefox but the loading screen doesn't show any progress. Unity 2022.3.1f1


Found how to get error messages:



Edit: From here, disabling Brotli compression fixed this loading error.

 

You need to make changes to see what works and what doesn't since we don't know nothing about your project, and the errors are non-descriptive. Have you tried building a new, empty project? Other browsers? Various build/player settings?

 

Clean new, empty WebGL 2022.3.1f1 project has the same issue - nothing loads.

 

How do you run it? Under Build Settings use "Build & Run" because if you build it and try to run it locally by opening the html file it won't work without a webserver running (something like that).

And be sure to check another browser. I recently did an URP postprocessing test for WebGL and both on my and a friend's machine it would run only at 35 fps looking in a specific direction, whereas Chrome ran the same spot with >60 fps. A few years back it used to be the opposite where Firefox was typically fastest for WebGL. Not sure what happened there, or whether it simply doesn't do postprocessing very well.

 

Yes, build and run. Basic 2D template. I can build and launch into FF from Unity 2020 but not 2022. Is there a way to redirect the launch browser or do I need to change my Windows default?

Searching the net, disabling Brotli compression for Gzip fixes the app loading.

 

I think it uses the default browser.
You can also install the WebGL Publisher package from Package Manager and upload it directly to Unity Play so you can always play the latest version and share it with others.

 

Was thinking about itchIO - forgot about Unity Play.
