Hey!

I'm trying to use the traefik as UDP Load Balancer, I created the deployment, service, udp ingress route also created a UDP entry point but I keep receiving this error `Error syncing load balancer: failed to ensure load balancer: failed to build load-balancer request: no health check port of protocol TCP found`, and I don't know how should I fix this.

Hi @tothalex,  
Thanks for your interest in Traefik.

It is actually hard to try to reproduce the issue. Could you provide us your configurations?

Hey @moutoum the issue was because of the platform, I used DigitalOcean. I moved on with AWS so what I did is that I deployed a kubernetes cluster to a EC2 instance with kops, but now I have a different issue `Protocol UDP is not supported by LoadBalancer`. This error is inside of the `service/traefik-udp` events. So my question is how can I fix this? Am I need to use nlb with traefik in order to get this done or how? Where can I even use the traefik-udp service if neither DigitalOcean nor AWS EC2 can't launch the `service/traefik-udp`.

I just simply installed the traefik with helm by enabling the udp within the values

```auto
traefik:
  ports:
    udp:
      port: 3000
      expose: true
      exposedPort: 3000
      protocol: UDP

```

Hi @tothalex,

This error message comes from your kubernetes cloud provider.  
It means that AWS doesn't support your [LoadBalancer](https://docs.aws.amazon.com/eks/latest/userguide/alb-ingress.html) definition as I think you are using an [ApplicationLoadBalancer](https://docs.aws.amazon.com/eks/latest/userguide/alb-ingress.html) which is L7. I think you are right by saying that you have to use a [NetworkLoadBalancer](https://docs.aws.amazon.com/eks/latest/userguide/network-load-balancing.html). Luckily, kops supports this `LoadBalancer` mode since 1.19.  
Could you please have a look at [this](https://github.com/kubernetes/kops/issues/5762#issuecomment-740687749)?
