MQTT connection error: API key not found

Hello,

I am running TTS v3.18.1 on my server. I am using Node-Red to connect with MQTT to get the sensor data. I created API key for MQTT integration using TTS console. My Node-Red MQTT node shoes connected status and I am able to receive the data. However, on the TTS console live data stream it keeps showing Fail to connect to MQTT API key not found.

Why the console is logging an error here?

I am having the same issue with this. Did you find out what the problem was?

I updated TTS version and it got resolved.
