title: Connection Error: A connection attempt failed because the connected party did not properly respond after a period of time
body: <p>I'm developing some software in python that utilizes Steam APIs. I'm using Flask to run and test the python code. Everything was going swell, but now I'm getting this error (I haven't changed any code):</p>
  
  <blockquote>
    <p>('Connection aborted.', error(10060, 'A connection attempt failed
    because the connected party did not properly respond after a period of
    time, or established connection failed because connected host has
    failed to respond'))</p>
  </blockquote>
  
  <p>I have no idea why this error is coming up, because the code was working perfectly fine and suddenly the error comes up, and I haven't changed anything in the code or with my computer or Flask.</p>

  <p>I would like to have an explanation of what the error means, and why this is happening. Thanks in advance. I really appreciate the help.</p>
