Fix for Unity 2020 WebGL build stuck at 90%

Hey, just wanted to make this quick forum post if people are stuck with their WebGL builds getting stuck at 90% in Unity 2020. To fix it I went to Edit - Project Settings - Player - Publishing Settings, and change compression format from Brotli, to disabled. This worked for me so I hope I can help other people with this same issue.

 

You really helped me a lot, thank you.

 

Worked for me too, thanks!

 

Doesn't help in fact. Well yes, it can load from my local host this way (when I pick the Build and run option) but when I upload the build to web, it's always stuck on 90% and that's all.

(And I've tried many tips found online but no one hepled. Now I'm kinda confused... )

 

Hey! did you find a solution, I'm having the exact same problem, running on local host but not on website. thanks!

 

I am also facing the same problem.. Working in localhost but not in itch

 

Same problem here :/ Think I've tried all possible combination of build setting (player setting).

 

I had the same 90% problem when trying to run a minimal WebGL scene (cube, light, camera) from Unity 2021.3.11, which ran fine on my local host but not from a remote machine. None of the above fixes helped, and it was likely server configuration. I found that placing the attached file in the <Application>/Build folder fixed the problem for me. (remove .txt extension, added for uploading) This modifies the server (in my case IIS) configuration with a few needed mime types.

Hope this helps someone still having this problem. I'm not sure exactly where I found this config file online but it was very helpful so thanks to whomever!
