LAUNCHCC3220MODASF: TIDEP-0083: Connection to server failed.

Hi Matsuzaki,

I tested the TIDEP-0083 code with my setup and everything seems to work fine on my end.

Given that I cannot replicate this, some more debug information is necessary. In particular, when HTTPCli_connect() fails, it returns a generic error code (in your case -102) but also provides a more detailed socket error in httpclient->sockerr. In httphandler.c, ConnectToHTTPServer(), could you please add in a printout of that variable when you fail to connect like so:

int ConnectToHTTPServer(HTTPCli_Handle httpClient, HTTPCli_Params *params)
{
    long lRetVal = -1;
    struct SlSockAddrIn_t addr;


#if USE_PROXY
    struct sockaddr_in paddr;
    paddr.sin_family = AF_INET;
    paddr.sin_port = htons(PROXY_PORT);
    paddr.sin_addr.s_addr = sl_Htonl(PROXY_IP);
    HTTPCli_setProxy((struct sockaddr *)&paddr);
#endif

    /* Resolve HOST NAME/IP */
    lRetVal = sl_NetAppDnsGetHostByName((signed char *)HOST_NAME,
                                          strlen((const char *)HOST_NAME),
                                          &g_ulDestinationIP,SL_AF_INET);
    if(lRetVal < 0)
    {
        ASSERT_ON_ERROR(GET_HOST_IP_FAILED);
    }

    /* Set up the input parameters for HTTP Connection */
    addr.sin_family = SL_AF_INET;
    addr.sin_port = sl_Htons(HOST_PORT);
    addr.sin_addr.s_addr = sl_Htonl(g_ulDestinationIP);

    /* Testing HTTPCli open call: handle, address params only */
    HTTPCli_construct(httpClient);
    lRetVal = HTTPCli_connect(httpClient, (struct SlSockAddr_t *)&addr, HTTPCli_TYPE_TLS, params);
    if (lRetVal < 0)
    {
        UART_PRINT("Connection to server failed. error(%d)\n\r", lRetVal);
        UART_PRINT("Socket error reported: %d\n\r", httpClient->sockerr);
        ASSERT_ON_ERROR(SERVER_CONNECTION_FAILED);
    }
    else
    {
        UART_PRINT("Connection to server created successfully\r\n");
        g_intNetworkState = NETWORK_STATE_CONNECTED;
    }

    return 0;
}

and provide me the socket error code that is printed out?

Michael

Hi Michael,
Thanks for replying me.

I add a new UART_PRINT() and tried.

Can you figure out something from "-688" ?

Hi Matsuzaki,

Error -688 indicates that the root CA certificate file that you are using is incorrect.
I checked again today, and the current correct root CA cert to use is the "DigiCert Global Root CA" certificate.

Please follow the steps I provided in the E2E post that you have linked to copy the correct root CA onto the CC3220 using Uniflash. What part of copying the root CA cert didn't work well for you?

Regards,
Michael

Hi Michae,

I've been using "VeriSign Class 3 Public Primary Certification Authority - G5" certificate to be failed..

Now I tried "DigiCert Global Root CA" certificate.

and then, I got this message on my terminal window.(#define IBM_NET_TEST 1 in network_task.c)

I'm feeling I wanna toast toward your country.

but who knows to use "DigiCert Global Root CA" certificate?
How do you know that?

Hi Michael,

All right, I'll implement your code. thanks!
