CC3220SF: Connection with MQTT and X.509 - Bad ECC Curve

Hello,
I am just trying to use the MQTT client provided by TI.

My code looks like this: 

#define CLIENT_NUM_SECURE_FILES  4

char *Mqtt_Client_secure_files[CLIENT_NUM_SECURE_FILES] = {"key.pem","cert.pem","cacert.crt", NULL};

MQTTClient_ConnParams Mqtt_ClientCtx =
{
	MQTTCLIENT_NETCONN_URL | MQTTCLIENT_NETCONN_SEC,
	SERVER_ADDRESS,  //SERVER_ADDRESS,
        SECURED_PORT_NUMBER, //  PORT_NUMBER
	SLNETSOCK_SEC_METHOD_TLSV1_2,
	SLNETSOCK_SEC_CIPHER_FULL_LIST,
        CLIENT_NUM_SECURE_FILES,
        Mqtt_Client_secure_files
};

When I try to call MQTTClient_connect(), I am getting error -751, which corresponds to a SL_ERROR_BSD_ESEC_ECC_CURVE_ERROR (-751L) /* Bad ECC Curve */

My certificate is generated with secp256r1, which I would like to use. Below, there is a communication between the device and mqtt broker.

Then the CC3220 calls (FIN, ACK) and returns the error. I believe, the main issue is Named Curve: x25519 from the Server Hello. I tried a different client on different platform, but using same certificates and I can see, that different platform is having in the Client Hello some sort of supported curves.

                    .....

Is it possible to set something similar on CC3220? Or do you think there is another issue in that? 

Thanks for the ideas!
