When does this happen?

IF ReadTimeout errors when exporting spans to Langfuse Cloud (e.g., 'requests.exceptions.ReadTimeout' or 'DOMException [TimeoutError]')

How others solved it

THEN Increase the client-side timeout by setting `LANGFUSE_TIMEOUT` environment variable to a higher value (e.g., 30 seconds) or by passing a `timeout` argument to the Langfuse client. Reduce the batch size by setting `LANGFUSE_FLUSH_AT` to a smaller number (e.g., 64). For OpenTelemetry exporters, set `OTEL_EXPORTER_OTLP_TIMEOUT` and `OTEL_EXPORTER_OTLP_TRACES_TIMEOUT` to 30000 milliseconds. Enable debug logging with `LANGFUSE_DEBUG=True` to diagnose further.
