Has anyone run into issues with

k8s-infra

trying to connect

otel-collector

over ingress ? I guess this error

Copy code

This is my

ingress

spec

Copy code

spec:
  ingressClassName: nginx
  rules:
  - host: <http://otelcollector.mydomain.com|otelcollector.mydomain.com>
    http:
      paths:
      - backend:
          service:
            name: rollstack-signoz-otel-collector
            port:
              number: 4317
        path: /
        pathType: ImplementationSpecific

I am using port

which should be the

grpc

port, right? so it’s a grpc to grpc connection but I don’t get why it’s failing anyone knows ?

In cases of some SDKs, you would have to include
https://
prefix for
OTEL_EXPORTER_OTLP_ENDPOINT

@Saad Bahir Please try with appending

https

in host URL
