Google Cloud Global Forwarding: Invalid value for field resource.IPAddress

Question

I am trying to implement https support for my GCP VM. For the purpose, I created all the load balancing components i.e. instance group, health check, backend service, url map & target proxy. All were created without error. However now when I am creating a global forwarding rule for the final step, I am getting the following error:

ERROR: (gcloud.compute.forwarding-rules.create) Could not fetch resource: - Invalid value for field 'resource.IPAddress': '35.xxx.xxx.xxx'. Invalid IP address specified.

I am using the following command:

gcloud compute forwarding-rules create fa-global-fwding-rule-1 --target-https-proxy=fa-https-proxy-1 --ports=443  --global --address=35.xxx.xxx.xxx

(IP add digits masked with xxx)

What am I missing?

I already have a working VM instance through http where I had promoted its ephemeral address to a static address (above is the same address 35.xxx.xxx.xxx)

Also once I implement https support, I want the http connect to continue working as well so that my existing apis are not disturbed until I move them to https

Any advice/help?

GCPs Load Balancer does not check to see if the static IP you picked was regional or global. If you accidentally reserved a "regional" IP instead of a "global" IP, it throws that silly error:

Invalid value for field 'resource.IPAddress': '35.xxx.xxx.xxx'. Invalid IP address specified.
