Fix MaxRetryError

✅ Solution

MaxRetryError in OpenTelemetry often occurs when the exporter fails to connect to the backend (e.g., OTLP collector) due to network issues or incorrect endpoint configuration and repeatedly retries, exceeding the maximum retry attempts. To fix this, verify the backend address is correct and reachable from your application, and consider increasing the `OTEL_EXPORTER_OTLP_METRICS_RETRY_MAX_ATTEMPTS` or `OTEL_EXPORTER_OTLP_TRACES_RETRY_MAX_ATTEMPTS` environment variables to allow more retries, or implement exponential backoff with jitter in your exporter configuration for improved resilience. Additionally, examine backend logs to troubleshoot potential server-side issues preventing successful connection.
