cgi から get リクエストすると権限エラーになる

--解決しました。ベストアンサーでいただいた内容ですが、書いておきます。ありがとうございます。

$ sudo gestsebool httpd_can_network_connect on

を設定したら動く様になりました。

こちらを見させていただきました。

http://hogehogehoge.jp/index.rb をブラウザで開き、index.rb の中で open_uri で外部サーバからデータを取得しようとすると権限エラーが発生して何も取得できません。
しかし何の権限なのか分かりません。何の権限をどう直せば良いでしょうか。

ruby
1index.rb
2
3require 'open-uri'
4url = 'https://hogehoge.com?sample.cgi?a=1&b=2&c=3'
5io = OpenURI.open_uri(url)
6puts io.read

hogehogehoge.jp にターミナルからsshでアクセスして直接 ruby index.rb を実行すると取得できます。

以下ブラウザから実行時のエラーメッセージ
