We are sending the APM on port 4318

package.json

@Vishal Sharma plz look

"@opentelemetry/auto-instrumentations-node": "^0.39.4",
    "@opentelemetry/exporter-trace-otlp-http": "^0.44.0",
    "@opentelemetry/sdk-node": "^0.44.0",
    "@opentelemetry/semantic-conventions": "^1.17.1",

We are using the above otel dependencies with respective versions @Vishal Sharma

@Aniket Singh There’s reported issue with v0.44. try downgrading

@opentelemetry/exporter-trace-otlp-http

to

0.43.0

for now. https://github.com/open-telemetry/opentelemetry-js/issues/4202

Thanks @Vishal Sharma, this helped. We are able to send traces now

Thank you @Vishal Sharma for quick help
