WebGl errors: Unable to parse Build/WebGL NNG.framework.js.br

I get this error when i deploy my webgl beta game any fixes?

Unable to parse Build/WebGL NNG.framework.js.br!

This can happen if Build Compression was enabled but web server hosting the content was misconfigured to not serve the file with HTTP Response Header "Content-Encoding: br" present.

Check browser Console and Devtools Network tab to debug.
