I made a webGL game, and the zip folder is 1.1GB.  I asked for more space and I upped my upload limit to 4 GB. Then I tried uploading it through Butler, after editing the game and saying that "this game will be played in the browser" it gives this error: 

There was a problem loading your project:

Zip contains file that is too large (officialRelease/Build/officialRelease.data.unityweb)

Please try deleting the ZIP file and uploading another one.

I deleted the zip file, and tried uploading through the website and got the same error, this also happened when I made another build. I dont know why its happening I thought it was because I did not have a cover image so I made a quick one but that was not the issue(idk why I thought it was honestly). 

so when the file uploaded with Butler, it ticked the "web" button and it still gave me the error. Even when I uncheked it and said "it will be played in the browser"  I STILL GOT THE ERROR. I dont know if my build is messed up or not. All my unity files are converted to WebGL and so is my build. In the zip file when I open it, I see a "Build" folder, a "TemplateData" and a "index" as a Microsoft Edge file. Do I have to switch to Chrome or is there another issue. Please help.

We have these limits for a reason, if you aren’t familiar or capable of optimizing your game for browser play then we recommend offering it as a downloadable game.

Based on what I can tell about your game from the screenshots you provided on your page, 1GB seems abnormally large, which suggests you are using uncompressed or un-optimized file formats, or potentially including additional assets that you game does not even use.

Thanks
