Hii Kaleb,
I think I will give up on trying to get it working with TCPIP Stack 5, and try to fix the problem with Harmony project (at least this one is working). I can't spend time working on both and I don't seem to be getting anywhere.

Thanks for your help.

I did some more testing and found out that sometimes I get TCPIsConnected(mySSL.socket) = false after 4 passes through the loop (count1 = 4).
I haven't found out why this happens yet.

Thanks Kaleb for your quick reply.
I have tried again to see what error code I get. Below is more of the code.

    switch(hubClientState){
        case SM_HUB_HOME:
            ipChanged = FALSE;
            messageSentFlag = FALSE;
            errorMsgNo = 99;
            mySSL.socket = TCPOpen((DWORD)(PTR_BASE)&FCM_WEBSITE[0], TCP_OPEN_RAM_HOST, 443, TCP_PURPOSE_GENERIC_TCP_CLIENT);
        
            if(mySSL.socket == INVALID_SOCKET){
                errorMsgNo = 0;        
                hubClientState = SM_HUB_DISCONNECT; 
                break; 
            }        
            hubClientState++;
            Timer = TickGet();
            break;
        case SM_HUB_IS_CONNECTED:
            if(!TCPIsConnected(mySSL.socket)){
                if(TickGet()-Timer > 8*TICK_SECOND){
                    errorMsgNo = 1;        
                    hubClientState = SM_HUB_DISCONNECT; 
                }
                break;
            }
            Timer = TickGet();
            if (TCPIP_TLS_CreateConnection(&mySSL) != WOLFSSL_GLUE_TCP_OPEN){
                hubClientState = SM_HUB_DISCONNECT; 
                break;
            }
            hubClientState = SM_HUB_IS_SSL_CONNECTED;
        case SM_HUB_IS_SSL_CONNECTED:
            if(!TCPIsConnected(mySSL.socket)){
                hubClientState = SM_HUB_DISCONNECT; 
                break;
            }
            result = wolfSSL_connect(mySSL.ssl);
            if (result == SSL_SUCCESS){
                hubClientState = SM_HUB_SEND_MESSAGE;
                break;
            }
            else if (wolfSSL_get_error(mySSL.ssl, result) == SSL_ERROR_WANT_READ){
                ++count1;
                break;
            }    
            else if(wolfSSL_get_error(mySSL.ssl, result) == SSL_ERROR_WANT_WRITE){
                ++count2;
                break;
            }
            else{
                err = wolfSSL_get_error(mySSL.ssl, result);
                hubClientState = SM_HUB_DISCONNECT; 
                break;
            }
        case SM_HUB_SEND_MESSAGE:

After a number of SSL_ERROR_WANT_READ errors - count1 value varies, but is above 100, I get result value = -1.
And I get an error code err = -313 in err = wolfSSL_get_error(mySSL.ssl, result).
This error code is not listed so I don't know what it means.

I had a project working for a couple of years with PIC32 and MPLAB8 with TCPIP Stack v5.xx. Recently, google FCM stopped accepting SSL connection from my TCP Client.
I have to move to MPLAB X and Harmony. I used an example there which uses Wolf SSL and it was working fine. But after adding all the parts of my previous project (with a lot of pain) I found out the the Harmony TCPIP Stack stops responding (no receiving or sending). I use HTTP server, UDP server, TCP Client (with Wolf SSL) and check and update of IP. I believe (and a lot of other people on Microchip forum) that MPLABX and Harmony are not fully developed/debugged applications.

Then I tried to port the example code from Harmony to MPLAB 8 and TCPIP Stack v5.xx. I changed Wolf SSL configuration file to use this stack but it doesn't work.
It fails on wolfSSL_Connect(mySSL.ssl) with the result SSL_ERROR_WANT_READ. I have searched the forum about this error but it doesn't give me any solution.
Small part of the code is below:

    if(!TCPIsConnected(mySSL.socket)){
        hubClientState = SM_HUB_DISCONNECT; 
        break;
    }
        int result = wolfSSL_connect(mySSL.ssl);
        if (result == SSL_SUCCESS){
            hubClientState = SM_HUB_SEND_MESSAGE;
            break;
        }
        else if (wolfSSL_get_error(mySSL.ssl, result) == SSL_ERROR_WANT_READ){
            break;
        }    
        else if(wolfSSL_get_error(mySSL.ssl, result) == SSL_ERROR_WANT_WRITE){
            break;
        }
        else{
            int err = wolfSSL_get_error(mySSL.ssl, result);    
            hubClientState = SM_HUB_DISCONNECT; 
        }

Any suggestions what I can do?
I am using Wolf SSL version 3.9.0 - which comes with Microchip Harmony.
Is there any working example of TCP Client with Wolf SSL for PIC32 and MPLAB 8 with TCPIP Stack v5xx?
Just remembered that I am using FreeRTOS but I haven't enabled it in the configuration file. Could it be the issue?
