selenium webdriver:edgeを実行してもブラウザが起動しません　Unable to parse remote response: Unknown error

リモート環境でselenium-hubを使用してedgeを立ち上げようとしましたが、ブラウザが起動した後、googleの画面が立ち上がる前にエラーになりました。解消方法などあればご教授いただけると助かります。

●エラーメッセージ

9browser = webdriver.Remote(
10    command_executor=command_executor,
11    options=options) #ここでエラー、ブラウザは起動し、初期画面は表示される

13browser.get("http://www.google.com")
14browser.quit()
