gloo: useProxyProto not working?

Describe the bug My envoy proxy fails to forward traffic properly when I enable useProxyProto in my Gloo gateways and set the corresponding field for AWS

service.beta.kubernetes.io/aws-load-balancer-proxy-protocol: '*'

I get unexpected response status code 502 when accessing the proxy.

Have you seen this before?

This bug does NOT occur if useProxyProto is true and the annotation is NOT applied.

Version 0.20.8
