Changed my Unity version from 2019 to 2020 now WebGL not working

Hi,
I've updated the Unity version which I use to create my WebGL application, and now the build folder is filled with GZIP files, before it was not, and these files don't work on my site. I've checked with this tool:
https://smallseotools.com/check-gzip-compression/
and my site is supporting GZIP. What could be the problem?

 

You need to configure your server to serve js.gz and wasm.gz as JavaScript and WASM files instead of GZIP files.
More info:

Thanks for the answer,
on the first link I saw this:
"Disables compression. Use this option if you want to implement your own compression in post-processing
scripts. You should also use it if you plan to use static compression on the hosting server."
What is the meaning of static compression. I know that my server is supporting GZIP compression. I checked on this link: https://smallseotools.com/check-gzip-compression/
Does this mean "use static compression on the hosting server"?
And why should I not use compression? because the server is using it already, and there is no need, or will it also cause conflict and cause my WebGL build not to work?
