Block by CROS

I have recently checked my web site and found these problems, may I ask you to assist me?

Access to font at ‘https://pub-91b8ec6f0b2d4a69ad17bf5fa477a0cb.r2.dev/pull-assets/webfonts/fa-solid-900.woff2’ from origin ‘https://www.lovepei.net’ has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource.
solid.min.css:1

I can click add the CORS but I don’t know how to write it.

did any one can give me a hand?
