I want to connect to Azure Iot Hub, with Python MQTT.
An username and SAS token is required by Iot Hub. This is my code:
import paho.mqtt.client as mqtt
def on_connect(client, userdata, flags, rc):
print("Connected with result code "+str(rc))
client.subscribe("$SYS/#")
def on_message(client, userdata, msg):
print(msg.topic+" "+str(msg.payload))
client = mqtt.Client()
client.on_connect = on_connect
client.on_message = on_message
client.username_pw_set("myHub.azure-devices.net/device1", "mySASToken")
client.connect("myHub.azure-devices.net", 1883, 60)
client.loop_forever()
But after running for a while, this exception is thrown:
TimeoutError: [WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond
Does somebody know why I can't connect to the Iot Hub?
