I'v created a MQTT node and which i have linked with influx DB node. My mqtt node is supposed to be connect with my device on the TTN "co-sensor1". I have followed all the steps to set up the mqtt node that TTN has posted \< [MQTT in Node-RED [HowTo] - Application Development - The Things Network](https://www.thethingsnetwork.org/forum/t/mqtt-in-node-red-howto/39909) \> but for some reason my node is stuck on " connecting "

Also when I try to paste the mqtt access key that I have generated from TTN onto my password section it keeps disappearing when I deploy it and often shows the old passcode that I have used for a previous application.

Before all this all went left I was receiving errors to change my credential secrets which I'm showing below. I edited out what actually there so will just say I wrote "pineapples2".

I don't know if this is what I did wrong or not so if you have any idea on how I can fix this issue please let me know.

I think you should be using port 8883 for secure MQTT connections!

Well spotted.

From [API Reference | The Things Network](https://www.thethingsnetwork.org/docs/applications/mqtt/api/index.html) ...

> API Reference
> 
> - Port: `1883` , or `8883` for TLS
