Description

If you build or use the precompiled binaries, and run FS headless, it's not able to resolve the challenge when also using a proxy (no authentication).

So to be clear:

• no authentication, so it's not related to Proxy authentication not working #1534
• running from source works in all tested scenarios
• running headless works without proxy
• running headful works with and without proxy
