accessing service form another pod Kubernetes - nginx

Question

I have two services running in my k8s.
I am trying to access my wallet service from my user service but my curl cmd just returns 504 gateway timeout.
here is my ingress
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: dev-ingress
namespace: dev
annotations:
nginx.ingress.kubernetes.io/ssl-redirect: "false"
# nginx.ingress.kubernetes.io/use-regex: "true"
# nginx.ingress.kubernetes.io/rewrite-target: /api/v1$uri
spec:
ingressClassName: nginx
rules:
- http:
paths:
- path: /api/v1/wallet
pathType: Prefix
backend:
service:
name: wallet-service
port:
number: 80
- path: /api/v1/user
pathType: Prefix
backend:
service:
name: accounts-service
port:
number: 80
this is the way I passed the env in my account service.
http://wallet-service:3007
and I log the URL when hitting my endpoint
curl http://EXTERNAL_IP/api/v1/user/health/wallet
every other non-related endpoint works.
Any help is appreciated

Do you have an actual K8S service?
apiVerison: ...
kind: Service
Check it with kubectl get svc -A and you should see your services there
Check to see that your pods are exposed to the services
kubectl get endpoints -A
Are you running on a cloud provider (GCP, Azure, AWS, etc), if so check your security configuration as well (NSG for Azure, a security policy for AWS, etc)
Check inner communication :
# Log into one of the pods
kubectl exec -n <namespace> <pod name> sh
# Try to connect to the other service with the FQDN
curl -sv <servicename>.<namespace>.svc.cluster.local
Update:
You commented that you are running on Azure, check the desired ports are opened under the NSG.
Assuming that you are running AKS you need to find out the MS_xxxx resource and your NSG group will be located under this resource group, edit it and open the desired ports
You are trying to connect to http://wallet-service:3007/api/v1/wallet/health - Where did you get the 3007 port?
