Hi Nimesh,
Another thing is that you need to recompile the WolfSSL library after the above changes
If you are not aware about how to compile, please refer:

Hi Nimesh,
Sorry for a late reply.
1. I use the same versions for both.
2. Please refer to WolfSSL manual https://www.wolfssl.com/wolfSSL/Docs-wo … l-toc.html
To enable debug option open WolfSSL source file "C:\ti\wolfssl\wolfssl\wolfcrypt\settings.h" (Assuming you have extracted the WolfSSL source to "C:\ti\wolfssl") and under line "#ifdef WOLFSSL_TIRTOS" add line "#define DEBUG_WOLFSSL"
In your application code include the headers:
#include <wolfssl/ssl.h>
#include <wolfssl/wolfcrypt/logging.h>
and call the following functions:
wolfSSL_Debugging_ON();
wolfSSL_SetLoggingCb(log_function);
void log_function(const int logLevel, const char *const logMessage)
{
// USE SYSTEM PRINTF to outpul SSL logs to console
}
3. To enable the required cipher suite
In step 2, add the following line also
#define WOLFSSL_STATIC_RSA
Hope this helps.
Thanks
Hi Nimesh,
I guess you may get the same error code for multiple issues and my troubleshooting steps may not apply directly to yours.
Anyways, I am posting the troubleshooting that I did.
My exact issue was that the SSL server always sent a TCP_RESET immediately after I sent CLIENT_HELLO message due to the required cipher suite(TLS_RSA_WITH_AES_256_CBC_SHA) not being advertised in CLIENT_HELLO message.
The issue was resolved by enabling the required cipher suite with the...
#define WOLFSSL_STATIC_PSK - This is a typo, he meant to say:
WOFLSSL_STATIC_RSA
- Kaleb
... and recompiling and linking the Wolf-SSL library with my application code.
Hope this helps.
Thanks,
Akshat
Hi Kaleb,
Thanks for your reply.
My project has just started and I may need tons of support in future and may need to bother you.
Thanks,

Hi malikfehan123
Thanks for your post.
I got the logs by enabling debug prints in WolfSSL library.
After much debugging, I was able to find the exact issue and the define to enable the required cipher.
My issue is solved now.
Thanks,
Akshat
I am using WolfSSL v 3.10.2 with TI-RTOS and I get socket error -308 while connecting to my corporate's cloud server.
After enabling WolfSSL logs I see that during SSL handshake, the server sends a connection close (may be a TCP reset) immediately after my device sends CLIENT_HELLO.
Logs are attached for reference.
Please let me know the possible causes of connection close immediately after sending CLIENT_HELLO, Is there anything to be enabled on WolfSSL side? Also, excuse me as I am not an SSL expert here.
Another input is that I also tried to replicate the behaviour with openssl, but does not see the error and SSL handshake is always successful . The cipher suite that is negotiated between openssl and the problematic server is AES256-SHA (TLS_RSA_WITH_AES_256_CBC_SHA).
Please advise.
Thanks,
Akshat
