Hi,

I have no idea which category I should post my issue.

My issue:  
I am getting this output with node.js and the node.js example from [https://www.thethingsnetwork.org/docs/applications/nodejs/quick-start.html](https://www.thethingsnetwork.org/docs/applications/nodejs/quick-start.html).

Error { Error: 14 UNAVAILABLE: Connect Failed  
at Object.exports.createStatusError (C:\Users\A686269\Documents\mqttTTN\node  
\_modules\grpc\src\common.js:87:15)

\_interceptors.js:867:24)  
code: 14,  
metadata: Metadata { \_internal\_repr: {} },  
details: ‘Connect Failed’ }

Can someone explain me why this is happening?

Thanks in advance.

Nevermind I fixed it. To everyone having this issue in the future, youre probably on a vpn or there is some issue with your pc’s wifi. Switching to a 4G wifi hotspot fixed it for me.

I’m also seeing that with a wired connection.

Question: what was the issue and waht was the fix?

Greetings, Karin

See [Node-RED “Error: 14 UNAVAILABLE: Connect Failed” when using node-red-contrib-ttn](https://www.thethingsnetwork.org/forum/t/node-red-error-14-failed-to-connect/19742/12) which suggest to use Node-RED’s built-in MQTT nodes, rather than the advanced/complex one offered by TTN.

(Indeed, I’ve always used the built-in MQTT nodes, without any problems.)
