Hi!  
I recently started working on a project in which to implement the control of a device using the mqtt protocol.  
I chose HiveMQ because I liked the clear and intuitive interface for configuring a mqtt broker.  
I tried using the adafruit mqtt library, inspired by [this topic](https://community.hivemq.com/t/arduino-example-with-server-signed-certificate/502), but no success.  
File adapted from example:  
[https://github.com/adafruit/Adafruit\_MQTT\_Library/blob/master/examples/adafruitio\_secure\_esp8266/adafruitio\_secure\_esp8266.ino](https://github.com/adafruit/Adafruit_MQTT_Library/blob/master/examples/adafruitio_secure_esp8266/adafruitio_secure_esp8266.ino)  
I got error: Connecting to MQTT… Connection failed

I mention that I took the login data from the HiveMQ configuration console, and the fingerprint from the browser connected to the same console. What am I doing wrong?  
Does anyone have a basic example for using a mqtt broker with the esp8266? What library works? Is it possible for the esp8266 to use a certificate instead of the inconvenient fingerprint solution?

Hi @Vlad ,

Great to see your interest in MQTT and HiveMQ, welcome to the community!

Please refer to the HiveMQ Cloud’s [Getting started with Arduino ESP8266](https://console.hivemq.cloud/clients/arduino-esp8266) guide.

I hope this helps.  
Kind regards,  
Dasha from HiveMQ Team
