### App Id

dqbbd1fflds4t

### Region

us-east-1

### Amplify Hosting feature

Redirects

### Describe the bug

Rewrite entry on redirects doesn't work when pointing to an AWS Application Load Balancer.

### Expected behavior

Should work.

### Reproduction steps

Just hit: https://localizalia.dqbbd1fflds4t.amplifyapp.com/api/session
It's random, sometimes it works, but usually it gets stuck at the second time you try.

### Build Settings

```yaml
rewrite entry not working:

{
"source": "/api/<*>",
"target": "https://xxxxx-my-alb/api/<*>",
"status": "200",
"condition": null
}
```

### Additional information

I suspect this has to do with tls1.3 because I see it in access logs and it is not supported by ALB.
Here's the log with two requests. One times out after 300 seconds and we get a response. The other returns an error because I closed the browser. The request should return instantly.

Start by reproducing the rewrite at https://localizalia.dqbbd1fflds4t.amplifyapp.com/api/session using the Build Settings entry targeting the Application Load Balancer. Review the attached access-log CSV and the reported 300-second timeout, then determine whether the rewrite reliably returns the ALB response. Done means the request works consistently and promptly.
