Noodl uses websockets for MQTT, not raw TCP connections, so the URLs that Shiftr gives you need to be modified slightly:
If you’re running Shiftr locally use port 1184:
For the cloud version use, make sure you connect via mqtts:
mqtt:// will actually resolve to
ws:// under the hood, and
wss://, since browser don’t support raw TCP connections due to security concerns. Luckily, as can be seen above, Shiftr support websockets.
