Python requests hangs when script launched through crontab

Question

I've got a Python script which downloads data in json format through HTTP. If I run the script through command-line using the requests module, the HTTP connection is successful and data is downloaded without any issues. But when I try to launch the script as a crontab job, the HTTP connection throws a timeout after a while. Could anyone please tell me what is going on here? I am currently downloading data via a bash script first and then running the Python script from within that bash. But this is nonsense! Thank you so much!

Using: 3.6.1 |Anaconda custom (64-bit)| (default, May 11 2017, 13:09:58) \n[GCC 4.4.7 20120313 (Red Hat 4.4.7-1)]

P.S.: I haven't found any posts regarding this issue. If there is already an answer for this on some other post, then please accept my apologies.

This is an excerpt from my code. It times out when running requests.get(url):

try:
   response = requests.get(url)
   messages = response.json()["Messages"]
except requests.exceptions.Timeout:
   logging.critical("TIMEOUT received when connecting to HTTP server.")
except requests.exceptions.ConnectionError:
   logging.critical("CONNECTION ERROR received when connecting to HTTP server.")

I just found the answer to my question. I've defined the proxy being used and then used it like this in my code:

HTTP_PROXY="http://your_proxy:proxy_port"
PROXY_DICT={"http":HTTP_PROXY}

response = requests.get(url, proxies=PROXY_DICT)

Thank you all for your comprehension. I guess I should have done a thorough search before posting. Sorry.
