Hi Shruti, just to confirm are you configuring SSL connectivity with ThingWorx platform? Because the issue seems to be related to that, if ThingWorx is not configured for SSL connectivity please make sure it is. If in case you are not using SSL then make sure to disable it in the configuration file for CSDK.

    Hi Sushant

    I have disabled the SSL by modifying the twConfig.h  and twTls.h in c SDK file and I tried with the stream sensor example but the error is same and I have done the SSL setting with this  link No SSL certification in C SDK

    Shruti, would it be possible for you to share just the configuration part of your setup? One more thing, is the device running CSDK and ThingWorx are they both on different machines? If yes, are you able to reach ThingWorx URL from the device running CSDK? May be you could try pinging via the IP / or fully qualified domain name of the machine? Not sure if by any chance it's firewall somehow interfering with your connection
