HTTP::ConnectionError on HTTPS queries through HTTP proxies #685
Description
Hi,
We are using the http gem in Mastodon, and I've been reported failures when using a HTTP proxy.
Upon investigation, it seems it occurs directly in the http gem and only fails with HTTPS URLs.
Indeed, the following works:
HTTP.via('127.0.0.1', 8118).get('http://httpbin.org/get')But the following fails:
HTTP.via('127.0.0.1', 8118).get('https://httpbin.org/get')It fails with the following error:
/home/mastodon/live/vendor/bundle/ruby/3.0.0/gems/http-5.0.1/lib/http/connection.rb:108:in `read_headers!': couldn't read response headers (HTTP::ConnectionError)

from /home/mastodon/live/vendor/bundle/ruby/3.0.0/gems/http-5.0.1/lib/http/chainable.rb:20:in `get'

This also fails with http 5.0.0 but not with 4.4. Version 5.0.0pre3 seems to also work.
