I added all the configurations and headers needed in the server.
I tried to add the same request headers in the DNS configurations. Didn’t work

By default, Cloudflare should not block the CORS headers coming from your origin host/server.

Are you sending POST or? Did you also enabled and sent HEAD alongside?

Any blocked requests in the Security tab → Events (if you get 403, maybe some of the Security settings such as Managed Rules were triggered)? :thinking:
