Ingress Gateway: no routing, 404 Not Found

Hi Team!

#### Overview of the Issue
I'm trying to setup ingress gateway with routing based on `Hosts` field (or any simple setup, including wildcard on `Name` field).
Envoy always returns `404 Not Found`

#### Reproduction Steps
1. Create ingress gw. using this config:
```{
"Kind": "ingress-gateway",
"Name": "us-east-ingress",
"TLS": {
"Enabled": false
},
"Listeners": [
{
"Port": 80,
"Protocol": "http",
"Services": [
{
"Name": "pk-server",
"Hosts": [
"pk-api.example.com",
"pk-server.ingress.consul",
"*.consul"
]
}
]
}
],
"CreateIndex": 130475,
"ModifyIndex": 131469
}
```
2. Register consul service with connect proxy
```
{
"service": {
"port": 5002,
"name": "pk-server",
"connect": { "sidecar_service": {} }
}
}
```
3. Set proxy-defaults:
```
Kind = "proxy-defaults"
Name = "global"
Config {
protocol = "http"
}
```
4. Run connect proxy:
`consul connect envoy -gateway=ingress -register -service='us-east-ingress' -address 'xx.xx.xx.xx:80' -token='' -admin-bind='xx.xx.xx.xx:1900' -omit-deprecated-tags`

5. Try curl to the service:
```
curl -v -H "Host: pk-server.ingress.consul"
* Trying xx.xx.xx.xx:80...
* TCP_NODELAY set
* Connected to xx.xx.xx.xx (xx.xx.xx.xx) port 80 (#0)
> GET / HTTP/1.1
> Host: pk-server.ingress.consul
> User-Agent: curl/7.68.0
> Accept: */*
>
* Mark bundle as not supporting multiuse
< HTTP/1.1 404 Not Found
< date: Wed, 09 Dec 2020 14:26:12 GMT
< server: envoy
< content-length: 0
<
* Connection #0 to host xx.xx.xx.xx left intact
```
`curl` using any value from `Hosts` also failing.

### Debugging
Name resolution looks good:
```
dig +short @127.0.0.1 -p 8600 pk-server.ingress.consul SRV
1 1 80 0af00037.addr.pk.consul.
```

I am able to connect to service `pk-server` from other service via `consul connect proxy`
