k8s static router operator not forwarding traffic to my NAT gateway

Hello folks, I followed the instructions for setting up a nat gateway and a backend droplet it works fine, i can see traffic outgoing from the nat, my problem was in managed kubernetes I used the static router operator and seems okay I saw the deamonsets running, i added a static route object with all Frankfurt CIDRs public ip, as my vpc is there with all resources. but the traffic is not forwarded to the nat gateway I followed this tutorial https://sam-thomas.medium.com/how-to-setup-static-outbound-ip-in-digitalocean-kubernetes-doks-5cfb65e69165
