visual studio kubernetes project 503 error in azure - kubernetes

Question

I have created a kubernetes project in visual studio 2019, with the default template. This template creates a WeatherForecast controller.
After that I have published it to my ARC.
I used this command to create the AKS:
az aks create -n $MYAKS -g $MYRG --generate-ssh-keys --z 1 -s Standard_B2s --attach-acr /subscriptions/mysubscriptionguid/resourcegroups/$MYRG/providers/Microsoft.ContainerRegistry/registries/$MYACR
And I enabled HTTP application routing via the azure portal.
I have deployed it to azure kubernetes (Standard_B2s), with the following deployment.yaml:
# deployment.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
name: kubernetes1-deployment
labels:
app: kubernetes1-deployment
spec:
replicas: 2
selector:
matchLabels:

targetPort: http # Port to forward to in the POD
ingress.yaml:
#ingress.yaml
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: kubernetes1
annotations:
kubernetes.io/ingress.class: addon-http-application-routing
spec:

- host: kubernetes1.<uuid (removed for this post)>.westeurope.aksapp.io # Which host is allowed to enter the cluster

port:
name: http # Which port in that service
path: / # Which path is this rule referring to
pathType: Prefix # See more at https://kubernetes.io/docs/concepts/services-networking/ingress/#path-types
But when I go to kubernetes1..westeurope.aksapp.io or kubernetes1..westeurope.aksapp.io/WeatherForecast I get the following error:
503 Service Temporarily Unavailable
nginx/1.15.3

It's working now. For other people who have the same problem. I have updated my deployment config from:
# deployment.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
name: kubernetes1-deployment
labels:
app: kubernetes1-deployment
spec:
replicas: 2
selector:
matchLabels:
app: kubernetes1
template:
metadata:
labels:
app: kubernetes1
spec:
containers:
- name: kubernetes1
image: mycontainername.azurecr.io/kubernetes1:latest
ports:
- containerPort: 80
to:
# deployment.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
name: kubernetes1
spec:
selector: # Define the wrapping strategy
matchLabels: # Match all pods with the defined labels
app: kubernetes1 # Labels follow the `name: value` template

app: kubernetes1
spec:
