Cloudflare Zero trust not working over Arduino Ethernet HTTP reqeust

I'm currently working with an Arduino Nano to send HTTP requests to a Cloudflare Zero Trust endpoint. Despite disabling the “Always HTTPS on” setting in Cloudflare, I am still encountering an issue. The Arduino successfully receives the initial HTTP response headers, as shown below, but does not retrieve the expected JSON payload following the headers.

Could you advise on any further adjustments that might be necessary within the Cloudflare Zero Trust configuration to ensure the Arduino receives the full JSON response? Thank you.
