I have a couple of services and the loadbalancers work fine. Now I keep facing an issue with a service that runs fine, but when a loadbalancer is applied I cannot get it to work, because one service seams to be unhealty, but I cannot figure out why. How can I get that service healthy?

Here are my k8s yaml. Deployment:
