python pip install returns SSL error - python-2.7

Question

Recently I've started working at a large company. I've installed python and am now trying to install packages (using pip, which is installed) but get the following error (numpy is an example, but this error occurs for every package):
> pip install numpy
Collecting numpy
Could not find a version that satisfies the requirement numpy (from versions: )
No matching distribution found for numpy
Because I have the idea that I get the error because I'm in a corporate network I tried the following (because someone else on StackOverflow did so as well):
> pip -vvv install numpy
Collecting numpy

Can anybody tell me what is going wrong and how I can fix this? My work laptop runs windows 10.
I would be very grateful if somebody can help.

Answer 1

The problem has been solved. The company uses a proxy, if this is temporarily turned off I can install packages without a problem.
I hope this helps others in the same situation
