**Describe the bug**

My response to an http request is an application/octet-stream, using the cloudflare tunnel always receives the full packet before transmission, does anyone know what the situation is?

**To Reproduce**
---
only created the tunnel, configured the public host, not enabled the private network,

forwarded my http requests to my server tha build with this **https://github.com/Chanzhaoyu/chatgpt-web**

Express an vue3

If it's an issue with Cloudflare Tunnel:
---
4. Tunnel ID :
```a84fe929-20ee-426c-8690-a6389ec60268```
6. cloudflared config:

```yaml
url: http://127.0.0.1:3002
tunnel: a84fe929-20ee-426c-8690-a6389ec60268
credentials-file: /path to my cert-file/cert.json

application/octet-stream can streaming instead of receiving the full packet before transmission
