Hello, I am currently working on a project using STM32CubeIDE, where I am leveraging mbedTLS v2.16.2 to establish a secure MQTT connection with a Mosquitto broker on port 8883. During my implementation, I encountered a TLS handshake error with the following details: mbedtls_ssl_handshake failed. -29312 (-0x7280) I would like to confirm if mbedTLS v2.16.2, as provided in STM32CubeIDE, supports secure TLS connections (e.g., Secure MQTT) and is compatible with Mosquitto broker configurations. Additionally, I would appreciate guidance on resolving this error. Here are some specific details about my setup:
1. mbedTLS version: 2.16.2 (as integrated into STM32CubeIDE). 2. Broker: Mosquitto, configured for secure MQTT on port 8883. 3. Issue: TLS handshake fails with the error mentioned above. 4. Certificates: [Specify if you are using self-signed certificates, CA certificates, etc.]. Please let me know if additional information or logs would be helpful for diagnosing the issue. Thank you for your assistance.

And, are you using self-signed certificates, or what?
0x7280 means that the server closed the connection, likely something it didn't like... and you should probably read the server logs.
