Why is my Ingress Nginx serving HTTPS instead of HTTP in production?

I've got two environments set up, test and prod, both created with the same Terraform template, so they should be identical in configuration. Each cluster has Argo CD installed. The test cluster works well, but in the prod environment, I'm hitting a 502 Bad Gateway error. It seems like the Ingress Nginx is trying to connect via the HTTPS port, even though my ingress manifest specifies HTTP. Both Argo CD instances have the insecure flag set to true and are served on paths. When I port-forward to Argo CD directly, it works fine in both cases. Here's a snippet of the ingress configuration I'm using:

```
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: argo-cd
namespace: argocd
labels:
app.kubernetes.io/name: argo-cd
app.kubernetes.io/managed-by: manually-deployed
annotations:
kubernetes.io/ingress.class: "nginx"
nginx.ingress.kubernetes.io/force-ssl-redirect: "true"
nginx.ingress.kubernetes.io/backend-protocol: "HTTP"
spec:
ingressClassName: nginx
rules:
- http:
paths:
- path: /prod/argo-cd
pathType: Prefix
backend:
service:
name: argocd-server
port:
name: http
```

The only thing that's different between the test and prod environments is the path. I can access the test environment without issues, but when I try the prod environment, it results in a 502 error and shows that it's trying to use the argo-cd-server-https. Can anyone help me figure out why this is happening?
