cc @PeterDaveHello Anything you can do or is this going to be a server config issue?
@MattIPv4 not the same issue #13165 ?
@PeterDaveHello Actually could be, let me dig through what was said last time. I do recall someone saying the CORS issue was due to files 404-ing.
@carrbrpoa It looks as if this is actually part of the #13165 issue, please could you post there with full request/response headers of the failed request.
