Style sheet not loading

Since a few hours ago, I get this error loading style sheet for the Rocky forum (discourse):

The resource from “https://sjc6.discourse-cdn.com/standard14/stylesheets/color_definitions_rocky_1_1_accc6f3dd3d1a526e693a1e8c83a6e0e053a91f1.css.map?__ws=forums.rockylinux.org” was blocked due to MIME type mismatch (X-Content-Type-Options: nosniff).

Maybe someone changed the rules for loading the mime type?

Nope, more likely your local browser has an issue. Site working fine for me as always.

When I make a request to that url, I see these two headers

content-type: application/octet-stream
x-content-type-options: nosniff

Yes, I have also, but that is not causing any issues.
