1. OpenTelemetry OTLP Protocol Change

The default OTLP export protocol has changed from grpc to http/protobuf in line with the OpenTelemetry specification.

If you are using Jaeger or another OTLP-compatible collector, update your connection accordingly:

  • Or, to continue using the gRPC endpoint (port 4317), set:
OTEL_EXPORTER_OTLP_PROTOCOL=grpc
