I am unable to submit data to mqtt://demo.thingsboard.io. After calling esp_mqtt_client_publish() I get the following error: 

E (24381) MQTT_CLIENT: Read error or end of stream

If submitting to mqtt://iot.eclipse.org everything works as expected. Also tested also with the examples/mqtt_tcp app. Behaviour is the same. Eclipse works while Thingsboard not. Tested with both 3.1.1 protocol enabled and disabled. MQTT packets when inspected in Wireshark look the same.

Currently running out of ideas. Are there any known issues with Thingsboard or configuration changes I should try?

Are you subscribe or public on v1/devices/me/telemetry channel and using ACCESS_TOKEN as username? If not, please check here: https://thingsboard.io/docs/reference/mqtt-api/#mqtt-basics

It seems I was overthinking the problem. I was subscribed to v1/devices/me/telemetry but submitting to /v1/devices/me/telemetry. Thanks!
