Hey team !

I try to get traces from a java app. I have no access to the code source so I need to use the `javaagent`.


On the `.service` file I have added `Environment="OTEL_EXPORTER_OTLP_ENDPOINT=<http://localhost:4317>"`

The collector is setup with :
```receivers:
  otlp:
    protocols:
      grpc:
      http:

...

exporters:
  clickhousetraces:
    datasource: <tcp://10.24.208.77:9000/signoz_traces?username=signoz&password=signoz>
    timeout: 10s```

But I don't have any trace data.
In the journalctl of the collector I have

`Serve failed to create ServerTransport: connection error: desc = "transport: http2Server.HandleStreams received bogus greeting from client: \"POST /v1/traces HTTP/1.1\""`

Hey <@U08LBD49J2G>, What's the version of javaagent?

Yes it's seems to not wotk with gRCP protocol (why?).
Changing the port to 4318 to use http make it work

I don't know what is quarkus so I don't think so
