Hello! I am trying to connect to HiveMQ Cloud through Ethernet W5500 but I cannot connect correctly to the broker due to the RootCA, if you can help me it would be great!
Welcome to the community, @max1nl ! We’re glad to have you here.
It sounds like you’re having trouble connecting to HiveMQ Cloud due to the RootCA issue. You can download the root certificate here: https://letsencrypt.org/certs/isrgrootx1.pem. This will give you a file named isrgrootx1.pem, which you can use as your “Server Certificate”.
If you have any other questions or need further assistance, feel free to ask.
Best,

Thanks @Daria_H!
Sorry I didn’t fully explain my problem. I am using an M5Stack Basic (esp32) with the 5500 module and I am using the Arduino IDE. I previously connected it to WiFi with the WiFiClientSecure client and I was able to connect correctly. But now I need to connect it via Ethernet and I tried many tls/ssl libraries and I couldn’t connect to the broker. Could you please help me?
Hello @max1nl
Thanks for the clarification. I’m not very familiar with the Ethernet W5500 module but I guess you can use a wrapper library such as SSLClientESP32, that utilizes the same mbedTLS functionality under the hood and give it a try to add a secure connection to the MQTT Client object.
Kind regards,
