title: Python requests module exception SSLError
body: <p>I am getting a requests module exception error when I try to access the <a href="http://www.acastipharma.com/" rel="nofollow noreferrer">http://www.acastipharma.com/</a> website. I am not having problems with any other website so I believe this is a website specific issue. Here is some example code</p>
  
  <pre><code>import requests
  initialURL = 'http://www.acastipharma.com/'
  r = requests.get(initialURL)
  </code></pre>
  
  <p>When I run this code I get an error message that terminates with</p>
  
  <pre><code>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)'),))
  </code></pre>
  
  <p>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.</p>
  
  <pre><code>r = requests.get(initialURL, verify=False)
  </code></pre>
  
  <p>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.</p>
  
  <p>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:</p>

  <p>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</p>
