Hi,
The version of libcurl I am using is different in both systems
In windows ,the libcurl version is 7.15.1
And
In linux, the libcurl version is 7.16.1.

Even if it is because version difference , how can a higher version of
libcurl gives 'SSL level failed' error which a lower version does not give.
Below are the verbose output. Hope this is what you meant.
Thanks in advance.

In linux ,

Are you using the same libcurl version on both systems?

If so, can you please show us the full protocol dump of the command/response

communications when you run your app on these systems? (of course you should

edit out sensitive info before posting)
