Abhishek, given the vast amount of information you write, I suspect thisis not an HTTP error code (those are three digits, and the ones starting with 200 actually indicate a success), but rather a libcurl error code. Check against this list to find out whether that's an explanation: https://curl.haxx.se/libcurl/c/libcurl-errors.html
At least error 52 sounds familiar.
