OptionsRequestDenied When Uploading File to S3

Question

When I try to upload a JS file to S3, I get the upload error: OptionsRequestDenied. All the other files, including the JS ones have worked except this one.

The file makes some cross-origin requests using jQuery like this:

function corsRequest(callback){
  $.get("www.example.com", function(data, status){
    callback(data);
  })
}

setInterval(corsRequest, 5000);

I've tried changing the CORS settings to allow all methods:

<?xml version="1.0" encoding="UTF-8"?>
<CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
  <CORSRule>
    <AllowedOrigin>*</AllowedOrigin>
    <AllowedMethod>GET</AllowedMethod>
    <AllowedHeader>*</AllowedHeader>
  </CORSRule>
</CORSConfiguration>

However, OPTIONS is not allowed and returns the error:

Found unsupported HTTP method in CORS config. Unsupported method is OPTIONS

I even created a fresh bucket and it won't upload there either.

I can't find a reference to the error in the AWS docs. Any help would be appreciated.

Turning off any tracking blocker extension like uBlock Origin fixed it for me.
