Telegram and Mosquitto with TSL

Telegraf
,
1

Dear All,
i have a mosquitto broker that accept only TSL connection, below the configuration of telegraf consumer


[[inputs.mqtt_consumer]]
  servers = ["ssl://10.0.1.13:8883"]

  ## Topics that will be subscribed to.
  topics = [
    "mytopic/*"
  ]

 qos = 1

  client_id = "telegraf"

  ## Username and password to connect MQTT server.
  username = "user"
  password = "pwd"

  ## Optional TLS Config
 tls_ca = "/etc/telegraf/ca.pem"
 tls_cert = "/etc/telegraf/cert.pem"
 tls_key = "/etc/telegraf/key.pem"
  ## Use TLS but skip chain & host verification
 insecure_skip_verify = true

when run telegraf it raise an error

! [telegraf] Error running agent: starting input inputs.mqtt_consumer: not Authorized

The broker configuration is ok because mqtt explorer works fine with the same user&pass and certificate.

How i can debug in deep to understand the problem?

thank in advance!

Well that’s the answer from the server so there is something wrong with the authentication or authorization… Did you try to subscribe to the server topics from the Telegraf host with exactly the same credentials?

below the output of telegram consumer, i think the problem should be the mqtt versione protocol, is possibile?

Yeah it might be possible that the server expects another protocol version (likely v5)… Do you have access to the server log or can get the used protocol from a working client?

now is working, the problem was Mosquitto… It need to be rebooted when you create a new user and password…
thanks to all!
