Are your devices randomly disconnecting from your IoT Hub? Let's address the common culprits! Start with the basics that solve 80% of the issues: clock drift, DNS, and TLS. Ensure your device's time is accurate to avoid complications in cert validation. Check your MQTT/AMQP client settings, focusing on keep-alive and retry settings—aggressive timeouts can lead to connection flapping. Dive into your IoT Hub metrics, examining connections, connected devices, and any throttling errors. If a firewall is in place, verify that outbound ports are open and that deep packet inspection isn't compromising TLS. Finally, enable SDK logging to detect messages like “not authorized” or “server unavailable.” Tackle the root cause, not just symptoms, and watch your dashboards improve dramatically!
