Hi @SamuelCruz72

Welcome to the HiveMQ Community! 🎉

In the failing code, the certificate is stored as a `PROGMEM` string with inconsistent indentation. Ensure that lines between `-----BEGIN CERTIFICATE-----` and `-----END CERTIFICATE-----` are on separate lines, without leading spaces.

Refer to this working example for guidance: [ESP32 does connect to the server](https://community.hivemq.com/t/esp32-does-not-connect-to-the-server/3293/2).

Hope this helps! Let me know if you have any questions.

Best,  
Dasha from the HiveMQ Team
