<@U03KKRXNV9T> Are you using the OTLP exporter? there is likely a chance you are running into ssl/tls issues with exporter. Both SDK client and Collector need to by in sync. You may have to explicitly configure insecure connection on the exporter if you didn't setup any tls.

I have this
```          command: [ "opentelemetry-instrument", "--traces_exporter", "otlp_proto_http", "python3", "pywsgi.py" ]```
for my command. And I know I have the endpoint proper. it is the defaults set in the helm chart.

I am seeing this now
```2022-06-20T19:45:42.688Z	warn	zapgrpc/zapgrpc.go:191	[core] grpc: Server.Serve failed to create ServerTransport:  connection error: desc = "transport: http2Server.HandleStreams received bogus greeting from client: \"POST /v1/traces HTTP/1.1\""	{"grpc_log": true}```

What is endpoint set to? Does it have scheme https?

`OTEL_EXPORTER_OTLP_ENDPOINT: "<http://signoz-otel-collector.opentelemetry.svc.cluster.local:4317>"`

I have it the same way as I do on a NestJS app that is sending data

If you are using `otlp_proto_http` the port should 4318

I have tried both ports I can try changing it.

RPC framework <https://grpc.io/>. Something like thrift in apache land.

That's interesting my NestJS one works with 4317

Nice. Happy observing with SigNoz. You other app also works with 4317 but you explicitly mentioned you want to use proto_http instead of proto_grpc and In that case you need to make sure port is set correctly.
