When my domain is proxied, I am getting CORS errors.
Access to fetch at 'xxx' from origin 'yyy' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
When I use DNS only it works fine.
Doing a curl request seems to return status 444 from nginx on my server. I am not sure why.
Could this be because of HTTP2? Can I force usage of HTTP 1.1 using cloudflare?
