Selenium Grid Nodeがハブに接続できない

Question

MacでSelenium Gridハブを開始し、Mac上でWindows 7 VMにノードを設定しようとしています（VirtualBoxで動作している場合）。私は、Mac上でこのコマンドを実行しています：

java -jar selenium-server-standalone-3.0.1.jar -role hub 

そして私は恐ろしい

Nodes should register to http://10.10.3.1:4444/grid/register/ 
Selenium Grid hub is up and running 

を取得し、素晴らしいです。私はWindows VMに入り、次のコマンドを実行します。

java -jar selenium-server-standalone-3.0.1.jar -role webdriver -hub http://10.10.3.1:4444/grid/register -port 7777 -debug 

最終的にタイムアウトになり、接続できません。私は以下のデバッグ情報を貼り付けました。

*編集：私は窓のVM上のハブとノードの両方を実行しようとした、そしてそれは問題なく働きました。また、ハブとノードをMac上でのみ実行しようとしたところ、同じ問題が発生しました。その問題は何とか私のMacに関係していると私は言います。何をすべきかわかりません....

Answer 1

サーバーが判明しました。自動的にIPアドレスをハブに割り当てようとして間違ったものを選択しました。何らかの理由で、VPNゲートウェイのIPアドレスを選択していました。 -host 10.11.xx.xxを追加して私の問題を解決しました。
