How can I fix the CONNECTION_REFUSED error in my STM32 Nucleo H743ZI2 MQTT setup?
Hi @Daniel kalu , The
CONNECTION_REFUSED error typically indicates an issue with your MQTT broker settings or credentials. Double-check your MQTT broker’s IP address, port, username, and password. Also, ensure the broker is configured to allow connections from your device.6 replies
