Hello Lauri, Could you share your traefik definition? Looks like a configuration typo.

For my Traefik configurations I have following:

Copy code

# Configure ports
ports:
  # The name of this one can't be changed as it is used for the readiness and
  # liveness probes, but you can adjust its config to your liking
  traefik:
    port: 9000
    expose: false
    # The exposed port for this service
    exposedPort: 9000
    # The port protocol (TCP/UDP)
    protocol: TCP
  api:
    port: 8080
    expose: true
    exposedPort: 8080
    protocol: TCP
service:
  enabled: true
  type: ClusterIP

I’m not familiar with Traefik, looking at your K8s resources it looks ok. I’m going to try and get someone who might know more to you help you Lauri.

So are you using the reverse proxy from within the cluster as well? the above error is when frontend is unable to contact gms pod
