cafile C:\MQTT_Send_Service_TLM\PFE_2022_test_case_13\ca_public_certificate.pem
keyfile C:\MQTT_Send_Service_TLM\PFE_2022_test_case_13\server_private_key.pem
certfile C:\MQTT_Send_Service_TLM\PFE_2022_test_case_13\server_public_certificate.pem
tls certificates are generated by openssl 3.0.0 in windows machine
i have an embedded device running linux which have openssl 1.0.1p , i put the ca_public_certificate.pem generated in Windows machine in the embedded device and i try to connect to the broker with tls mode
