Resolution: it is likely that you've set up your proxies like this...

proxies = {
  "http": "http://myproxy.org",
  "https": "https://myproxy.org",
}

Using this setup, you're trying to connect to the proxy using HTTP for HTTP requests, and using HTTPS for HTTPS requests.

But if you get the error above, it is likely that your proxy doesn't support connecting via HTTPS. Don't worry: that's a common gotcha.

Change the scheme of your HTTPS proxy to http://... instead of https://...:

proxies = {
  "http": "http://myproxy.org",
  "https": "http://myproxy.org",
}

This can be simplified to:

proxies = "http://myproxy.org"
