Python アプリ エンジンの開発サーバーで 504 エラーに悩まされています。私は企業のプロキシの背後にいますが、通常は HTTP_PROXY と HTTPS_PROXY を設定しても問題はありません。それが私の問題に関連しているかどうかはわかりません。
私のコードでは、apiclient からの検出を使用しています (main.py 行 63)
driveService = discovery.build("drive", "v2", http=http)
これを実行すると、次のトレースバックが表示されます

同じコンソールウィンドウでcurlを使用して問題のあるURLを試すと、機能します（ただし、-kオプションを使用する必要があります）

App Engine と Python は初めてなので、少し迷っていることを告白します。どんな助けでも大歓迎です
