Hi Peter,
Thank you for bringing up the curl version concern. Last night, I attempted to connect using proxies directly with Python code on Ubuntu 16 (not using curl), but encountered the same issue.
Today, upon seeing your reply, I revisited the Python code and found the issue: there was a typo in the proxy URL đ
. Instead of https://address:8443, I mistakenly used http://address:8443.
Thank you so much for your help in getting this sorted out. I truly appreciate it!

OK, now I understand what you're trying to do, and I think I know what
the problem is. The support for HTTPS proxies in cURL was only added in
version 7.52, while Ubuntu 16.04 only has cURL 7.47. So if you're
running cURL from the same host that runs stunnel, Ubuntu 16.04's cURL
will not send the correct request. Try running cURL from another host, or
testing with `openssl s_client -connect address:8443` and then typing in
an HTTP CONNECT request by hand.
Hope that helps!
G'luck,
Peter
