<![CDATA[Mqtt will not publish.]]>I have an M5Stack core 2 that I'm trying to get to publish to a Mosquito broker installed in Home Assistant. I can subscribe fine but I just can't get it to publish. Is anyone else having issues with this? Could it be the firmware revision? I can send topics through Node Red and receive them fine but no matter what I try I can't get it to publish.

For comparison, this is mine for AWS MQTT.

Just a test setup at the moment. I can subscribe and get the topic message. When I press the buttons, the test display shows the buttons were pressed but the message does not post to the broker.
