Hi Manu,
It looks like you made a mistake on the client side configuring the certificate/private key. The client does not send the certificate and that corresponds to the error message on the server-side ("peer did not return a certificate").
Ciao Hannes

Greetings,
I am trying to connect from a STM32H7 MCU to a mosquitto peer, Can someone please help me to fix this issue that I have ?
I have used the DES3 cipher to create the keys ..
openssl genrsa -des3 -out test_ca.key 2048 ..
Fiddled quite a bit with buffers, stack, heap and mbedtls config, eventually the communication appears to be working, but the handshake appears to fail.
At the client MCU side, I see the mbedtls_ssl_handshake failed message with a return value of 0x7780
Additionally, I do see this message too: ssl_tls.c:5169: got an alert message, type: [2:40] ssl_tls.c:5177: is a fatal alert message (msg 40)
But unfortunately, I am unable to make out what the error message means.
At the peer, this is what i do see:
1598367067: New connection from 192.168.1.33 on port 8883. 1598367074: OpenSSL Error: error:1417C0C7:SSL routines:tls_process_client_certif icate:peer did not return a certificate 1598367074: Socket error on client <unknown>, disconnecting. 1598368366: mosquitto version 1.6.7 terminating
Someone, Please help !
Thanks, Manu
