I have setup self host

signoz

on kubernetes using signoz helm charts and then installed signoz otel agent using

k8s-infra

helm chart on another k8s cluster to export the metric but getting the following error:

{
  "level": "error",
  "ts": 1739957987.7333772,
  "caller": "exporterhelper/queue_sender.go:92",
  "msg": "Exporting failed. Dropping data.",
  "kind": "exporter",

  "error": "not retryable error: Permanent error: rpc error: code = Unknown desc = unexpected HTTP status code received from server: 0 (); malformed header: missing HTTP content-type",
  "dropped_items": 587,
  "stacktrace": "<http://go.opentelemetry.io/collector/exporter/exporterhelper.newQueueSender.func1|go.opentelemetry.io/collector/exporter/exporterhelper.newQueueSender.func1>\n\tgo.opentelemetry.io/collector/exporter@v0.109.0/exporterhelper/queue_sender.go:92\ngo.opentelemetry.io/collector/exporter/internal/queue.(*boundedMemoryQueue[...]).Consume\n\tgo.opentelemetry.io/collector/exporter@v0.109.0/internal/queue/bounded_memory_queue.go:52\ngo.opentelemetry.io/collector/exporter/internal/queue.(*Consumers[...]).Start.func1\n\tgo.opentelemetry.io/collector/exporter@v0.109.0/internal/queue/consumers.go:43"
}

Could someone please take a look and suggest some solution?
