python - Pythonスプリンターを使用してSeleniumリモート接続が拒否されました

Question

ブラウザのテスト用にスプリンターを試しています。残念ながら、ウェブサイトに接続できないようです。手動で行った場合、Web サイトはブラウザで正常に開きます。

私は何かを忘れましたか？splinter のドキュメント Web サイトの例に従いました。

私のpythonコード：

from splinter import Browser

with Browser() as browser:
    browser.visit("http://some-ip")

if browser.is_element_present_by_name("hour"):    
    browser.find_by_name("hour").fill("13")
else:
    print "No hour element"

スクリプト実行時のエラー メッセージ:
