Another "you have not yet finished authorizing this extension to use github" issue

Output/GitHub Authentication log から始め、プライベートリポジトリのクローンについて説明されているブラウザーのサインインフローを再現します。記載されている VS Code、macOS、Linux のセットアップ間で、報告された net::ERR_PROXY_CONNECTION_FAILED の結果を比較します。GitHub 認証が完了し、プライベートリポジトリをクローンできれば完了です。

Hi everyone,

I am one of those unlucky fellows with this error, and I haven't been able to find any solution yet.

I am using MacOS 15.5 build 24F74 and the following version of VS Code:

Version: 1.100.2 (Universal)
Commit: 848b80aeb52026648a8ff9f7c45a9b0a80641e2e
Date: 2025-05-14T21:47:40.416Z
Electron: 34.5.1
ElectronBuildId: 11369351
Chromium: 132.0.6834.210
Node.js: 20.19.0
V8: 13.2.152.41-electron.0
OS: Darwin arm64 24.5.0

My browser is Brave 1.78.102 (Chromium: 136.0.7103.113).

When I am trying to clone one of my private repos, VS Code tells me the extension GitHub wants to sign in using GitHub:

When I press the button, a new tab in my browser opens:

Finally, a pop-up message appears in the browser asking if I want to open VS Code, and when I agree, it throws me back to VS Code with this message:

At this point an error "ERR_PROXY_CONNECTION_FAILED" in the Output/GitHub Authentication appears:

2025-05-24 09:23:33.311 [error] net::ERR_PROXY_CONNECTION_FAILED

However, I don't have any proxy. I am also having the same issue on the latest builds of Manjaro and Ubuntu.

Switching to another browser or a different network does not help either.

I would highly appreciate any help, I am falling into despair and thinking about migration to GitLab and switching to some other IDE already, even though I don't want to. >__<'
