YouTube 以外のウェブサイトで Discourse が OneBox を生成できないことがわかりました。ログを確認したところ、次のエラーが発生していました。

`rails c` で `Oneboxer.onebox('https://bilibili.com')` を呼び出したところ、同じエラーが発生しました。

原因がわからず困惑しています。Discourse は OAuth や AI リクエスト、その他の HTTP リクエストはエラーなく処理できていますが、OneBox のみで発生し、YouTube OneBox は正常に生成されます。

現在プロキシサーバーを使用していますが、プロキシの問題ではないと確信しています。Python の `curl`、`wget`、`httpx` モジュールでは正常に応答を取得できましたが、Ruby の `excon` では `SSL: wrong version number` というエラーが発生しました。どうすれば修正できますか？

Ruby インタープリタのコンパイル時に使用した OpenSSL のバージョンは 2024 年 1 月に公開された `3.0.13` ですが、このバージョンは古すぎますか？

追加の補足: rails c で Excon.get を実行したところ、同じ結果になりました。これは excon ライブラリの問題でしょうか？

require "excon"
Excon::DEFAULTS[:include_default_port] = true

に置き換えてみてください。

Excon の設定ミスにより、HTTP プロキシを使用する際にポート番号が渡されていませんでした。その結果、プロキシサーバーはポート 80 を使用してリモートサーバーに接続していましたが、Excon は TLS を使用して HTTP コンテンツの復号化を試みていました。

良いですね！ワンボックスがうまく機能し始めました。
