Fix MaxRetryError

in OpenTelemetry

✅ Solution

MaxRetryError in OpenTelemetry usually indicates the exporter failed to connect to the backend (e.g., OTLP collector) after repeated attempts. Resolve this by verifying the backend address is correct and reachable from your application (check network connectivity, firewall rules, and DNS resolution). Also, ensure the backend is running and accepting connections.
