Where to find some data to connect the broker

Hello community, before we updated from lora to chirpstack I had a script where I managed a connection to the broker to obtain data, and these were the ones I used:

broker_address= ""  #Broker address
port = 1883                         #Broker port
user = "loraserver_app"                    #Connection username
password = "loraserver_app"            #Connection password
Keep_Alive_Interval = 60
Topic_subscribe = "application/+/device/+/+"

client = mqttClient.Client("Python")               #create new instance
client.username_pw_set(user, password=password)    #set username and password
client.on_connect= on_connect                      #attach function to callback
client.on_message= on_message                      #attach function to callback

but after the update they are failing with: Connection Refused so I guess the credentials I am using are not correct, I don’t remember where find certain data such as the user and password, I don’t know if it will be a standard or something similar, I would like you to help me find this new data, where can I get it?

Thanks in advance!

First of all, it would be good to know to which update you are referring :slight_smile:

In general, consult your MQTT broker configuration for the authentication options / configured credentials.
