SSL - Hardware acceleration function returned with error : UNKNOWN ERROR CODE (0015)

Hi.

I'm using mbedtls-SGX for a project and this piece of code keeps failing with various errors:

[&](uint64_t index) {
        client_opt_t opt;
        unsigned char buf[512];
        char port[10];
        client_opt_init(&opt);
        opt.debug_level = 1;
        opt.server_name = thread_info->platform_address;
        opt.request_page = "/incoming_trigger";
        opt.server_port = "8000";
        // disable certificate verification
        opt.auth_mode = MBEDTLS_SSL_VERIFY_NONE;
        // post request
        opt.request_type = DFL_POST;
        std::string payload = std::to_string(index);

        return ssl_client(
            opt,                    // Client options structure
            nullptr,                // Headers
            0,                      // Number of headers
            buf,                    // Output buffer
            sizeof buf,             // Output buffer size
            payload.c_str()         // Payload
        );
}

As I said the errors I get vary, here is the last I got were:

[ LOG] ssl_client:488: Seeding the random number generator...

Can someone help?
