I am encountering some errors when using the requests library for making requests to a particular website. At times, it works fine, but other times it returns an error. Can anyone assist me in identifying the issue and providing a solution? I am aware of the verify=False option, but I cannot use it due to security concerns.

I am trying to read data from an ESA server in a PyDev Eclipse 3.8.1 Environment using Python 3.5.3. An example of a product link is given here:
"https://scihub.copernicus.eu/dhus/odata/v1/Products('c7208694-dedb-4f47-96c0-c8fb03512ff5')
You will need authentication credentials to access the website.
In my Eclipse environment I have manually added in proxy settings by going to Windows-> General -> Network Connections. Authentication is not required for the proxy.
To get the content of the webpage, I use a Python get request to send my query as below:
url = r"https://scihub.copernicus.eu/dhus/odata/v1/Products('c5dc59f0-b041-4f76-a685-49be63491270')"
r = requests.get(url, verify=False, proxies=proxies, auth=auth)
I need the verify=False to disable the certificate check and proxies is a dictionary storing the proxy addresses with the relevant port. Server credentials are given with auth which is a tuple of a username and password.
When I send the request to the server, I get the following error:

I have tried the same request outside of Eclipse, in IDLE, and I am able to successfully connect and read the content. Is there something wrong with my current Eclipse/PyDev environment that will not allow me to send a get request?
Why is Python not able to connect? I am able to send get requests to this and other websites using other projects in Eclipse (e.g. https://podaac-opendap.jpl.nasa.gov/opendap/allData/oscar/preview/L4/oscar_third_deg/) with no problem whatsoever.
Edit: Added in versions
The socks timeout indicates that your problem is actually the connection to your proxy as opposed to the ESA server. Additionally, I believe the proxy settings in Eclipse are only used for plugins/software updates and not by any code you write.
As an initial step, check your proxy dictionary keys are correct and verify your proxy URLS if you can.
You mention you have other Eclipse projects that can access the internet; it's worth checking what proxy settings they implement and seeing if there are any discrepancies with your current setup.
I do not understand how to use urllib3 or requests to connect to an https web site. This is driving me nuts. I have installed certifi and I see the default .pem file it provides. I have tried to set the requests.verify option to requests to every .pem and .crt file on the machine my script runs on [I am not an admin on this device]. I get nothing but errors.
I switched to using urllib3 and am now getting:

It blows up on the raw_html = HTTP.request(... line. Ideas?
Edit
Huh, this has something to do with my target host. If I go to google.com then several of my pem/crt files work.
The problem is, you are using wrong certificate to make request.
you can run this command to verify which certificate is used when any request is made, and then use that certificate in your request,
openssl s_client -showcerts -connect google.com:443
Please also make sure that you are passing verify the path to CA_BUNDLE file or directory with certificates of trusted CAs.
This list of trusted CAs can also be specified through the REQUESTS_CA_BUNDLE environment variable.
If this doesn't work out for you can explicitly merge the environment settings into your session,
When you are using the prepared request flow, keep in mind that it
does not take into account the environment. This can cause problems if
you are using environment variables to change the behaviour of
requests. For example: Self-signed SSL certificates specified in
REQUESTS_CA_BUNDLE will not be taken into account. As a result an SSL:
CERTIFICATE_VERIFY_FAILED is thrown. You can get around this behaviour
by explicity merging the environment settings into your session:
from requests import Request, Session
s = Session()
req = Request('GET', url)
prepped = s.prepare_request(req)
# Merge environment settings into session
settings = s.merge_environment_settings(prepped.url, None, None, None, None)
resp = s.send(prepped, **settings)
print(resp.status_code)
I am getting a requests module exception error when I try to access the http://www.acastipharma.com/ website. I am not having problems with any other website so I believe this is a website specific issue. Here is some example code
import requests
initialURL = 'http://www.acastipharma.com/'
r = requests.get(initialURL)
When I run this code I get an error message that terminates with
requests.exceptions.SSLError: HTTPSConnectionPool(host='www.acastipharma.com', port=443): Max retries exceeded with url: /investors/ (Caused by SSLError(SSLError(1, '[SSL: SSLV3_ALERT_HANDSHAKE_FAILURE] sslv3 alert handshake failure (_ssl.c:645)'),))
An internet search indicates that the problem might be with acastipharma's SSL certificate. I tried installing pyopenssl to make sure I had the latest version of the the module thats checks SSL certificates but that did not solve the problem. I also tried running the requests.get statement with the verify=False option but that was also unsuccessful.
r = requests.get(initialURL, verify=False)
If anybody has any ideas on how to resolve this issue I would appreciate the assistance. I also tried using the older urllib.request package but ran into the same error.
This is an update to my original question: The error message I posted was from trying to run the requests command on one of the acastipharma's website subpages, here is the complete error message I get when I run the code exactly as shown in this question:

I am using Python 3.5.1. I am on a Mac using High Sierra version 10.13.2. I am using requests 2.18.4. Since posting the question I believe the problem lies with my IDE PyCharm's environment. If I use my Python 3.5 environment I have the problem as shown in this question, if I switch the project interpreter to a Python 3.6 Anaconda environment requests will work but unfortunately mysql won't import. Thanks
The OpenSSL version is OpenSSL 0.9.8zh 14 Jan 2016
This (very old and long unsupported) version of OpenSSL does not support the newer ciphers required by this specific web server. This server only supports ECDHE key exchange, which is not supported yet by OpenSSL 0.9.8. This means that the client only offers ciphers to the server which the server will not accept and due to no common ciphers the server will close the connection with an SSL handshake alert.
We can ignore this SSL Error using the following:
import warnings
from urllib3.exceptions import InsecureRequestWarning
warnings.simplefilter('ignore',InsecureRequestWarning)
I'm getting an SSLError while submitting a request against https://myaccount.xcelenergy.com (and am not nearly enough of an SSL expert to understand why). Can you help me see what the issue is (and how to address it)?

What I've Tried (to no avail)
# Specifically calling out local cert chain:
requests.get('https://myaccount.xcelenergy.com', verify='/usr/local/etc/openssl/cert.pem')
# Using Certifi's old chain:
requests.get('https://myaccount.xcelenergy.com', verify=certifi.old_where())
There is currently a known issue with OSX's Python3.6 and OpenSSL that might be related to what you're seeing. I was able to fix it by installing certifi, then making a symlink in OpenSSL's directory. All of that can be done for you by running the following from bash:
Applications/Python 3.6/Install Certificates.command
