I have one FE angular application hosted on EC2 instance which is not on cloudfare.
I have another BE Rails application which is accessible to FE via API and it is configured on Cloudfare.
FE can easily communicate with the BE application if I set the Proxy status is set to ‘DNS Only’ in cloudfare.
However, when I set the status to ‘Proxied’, I start getting CORS error in the chrome while trying to make request from Angular App to BE api.
If Cloudfare is disabled, I see the response headers like in network tab:
Access-Control-Allow-Methods: GET, POST, PUT, PATCH, DELETE, OPTIONS, HEAD
Access-Control-Allow-Origin: [FE ip/domain]
But enabling Cloudfare proxied status, starts throwing CORS error.
This issue is only happening on chrome.
