RPi2: Python requests fails for https (Errno 101)

Question

I'm trying to make my first web scraper and keep getting errors for https URLs but not http.

I am running Python 2.7.9 on RPi2 with Raspbian Jessie. I am also SSHing into the Pi on my laptop. All of this is being done at my home network.

I do not get these errors when running the code below on my laptop. Only when running it on RPi2.

I tried to find some solutions online and I found some people talking about issues with the proxy, but not sure if it applies here.

>>> import requests
>>> page = requests.get("http://www.google.com")
>>> page.status_code
200
>>> page = requests.get("https://www.timeanddate.com")
Traceback (most recent call last):

    r = adapter.send(request, **kwargs)

    raise ConnectionError(e, request=request)

Answer 1

I think that you are having timeout issues. Here is an example of 1 second timeout, which is working fine.

import requests

from requests.exceptions import ConnectionError
try:
   r = requests.get("https://www.timeanddate.com", timeout=1)
   print r.status_code
   print r.headers
   print r.encoding
   print r.text
except ConnectionError as e:
   print e
   r = "No response"

Answer 2

From the

Failed to establish a new connection: [Errno 101] Network is unreachable

error message, it seems that you are not able to connect to the server. Check that you can reach www.timeanddate.com on port 443 (HTTPS):

$ curl -I https://www.timeanddate.com

If you get something like:

HTTP/1.1 200 OK
(...)

then there may be some problem with your python installation. Else, you may have network issues. How is your PI connected to the internet?

Answer 3

I would try running : sudo pip install requests —upgrade
