GKE: ingress loadbalancer does not use configured static IP

Question

I've created a global static IP Address using terraform in GCP. However, when I try to assign it to an ingress controller inside a GKE cluster, it gets ignored:

Here's my kubernetes configuration:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
    name: homefully-ingress
    annotations:
        kubernetes.io/ingress.global-static-ip-name: "homefully-ingress-root"   
    labels:
        app: homefully-ingress
spec:
    # ...

the IP address referenced here looks like this:

NAME                    REGION        ADDRESS        STATUS
homefully-ingress-root  europe-west3  35.234.83.106  RESERVED

However, ingress does not use that IP Address but another random one. That's quite a problem, as I am not using google's DNS services, so I need to rely on a static IP.

Instead, this is what I am getting:

Name:             homefully-ingress
Namespace:        default
Address:          35.227.252.112

I can't find an error message or any hint on what's wrong here. Would be very thankful for some suggestions

stupid me - it was not a global ip address. in which case just a random new one got assigned
