TLDR Saad was experiencing connectivity issues with k8s-infra and otel-collector. vishal-signoz suggested appending https in the host URL which resolved the issue.

Has anyone run into issues with k8s-infra trying to connect otel-collector over ingress ?

I guess this error

2023-08-30T21:30:30.674Z    warn    zapgrpc/zapgrpc.go:195    [core] [Channel #6 SubChannel #7] grpc: addrConn.createTransport failed to connect to {
  "Addr": "",
  "ServerName": "",
  "Attributes": null,
  "BalancerAttributes": null,
  "Type": 0,
  "Metadata": null
}. Err: connection error: desc = "error reading server preface: http2: frame too large"    {"grpc_log": true}

This is my ingress spec

spec:
  ingressClassName: nginx
  rules:
  - host: 
    http:
      paths:
      - backend:
          service:
            name: rollstack-signoz-otel-collector
            port:
              number: 4317
        path: /
        pathType: ImplementationSpecific

I am using port 4317 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
