I'm facing an issue connecting STM32 to the MQTT broker.

What MQTT broker?

How are you trying to connect: Ethernet? WiFi? Other?

Are you sure that the basic IP connection is working?

Are you sure that your login/connection credentials & settings are correct?

the mqttstatus only reaches MQTT_CONNECT and then returns to MQTT_START instead of progressing to MQTT_RUNNING.

Sounds like the connection is failing

I'm using HiveMQ with Ethernet.
I'm certain it's working because I can ping that IP address.
When I log the status, it shows the connection state, but it doesn't reach the running state to send/receive data.

So have you resolved this question yet: https://community.st.com/t5/stm32-mcus-embedded-software/send-a-message-to-hivemq/td-p/733865 ?

So that's the basic IP connection.

Successful ping is certainly necessary - but may not be sufficient.

So look at what's necessary to get from 'connected' to 'running', and see where that's failing.

Is the connection dropping?
