https proxy not working with Cro::HTTP::Client

[CIAvash]

I tested the new proxy support, and https proxy doesn't seem to work.
Here is the code I tried:

use Cro::HTTP::Client;
my $resp = await Cro::HTTP::Client.get('https://httpbin.org/ip');
say await $resp.body;

Then I set HTTP_PROXY and HTTPS_PROXY to http://127.0.0.1:8118. The script hangs for a while and then prints Buf:0x<>.

When I try http://httpbin.org/ip, it works correctly.

Hi,

Can you please provide some more information on how to reproduce your bug?
I've tried with a few public proxies and was unable to do so.

I'm using Tor, and Privoxy for http(s) proxy.

I should say that my proxy works with curl and mojo command line tool.

Please tell me if you need more information.

Any idea if your proxy supports HTTP 2? Can you try using Cro::HTTP::Client in HTTP/1.1 only mode?

[jnthn]

Also, if you could set CRO_TRACE=1 in the environment and run it and put the output here, it may be useful.

I don't know, but enabling HTTP/1.1 had no effect.
