Homestead + Laravelで Vagrant upが出来ない

Laravel + Homesteadで開発をしています。
普段の環境では問題無かったのですが、帰省先の環境でvagrant upをすると

The specified host network collides with a non-hostonly network!
This will cause your specified IP to be inaccessible. Please change
the IP or name of your host only network so that it no longer matches that of
a bridged or non-hostonly network.

Bridged Network Address: '192.168.10.0'
Host-only Network 'en0: Wi-Fi (AirPort)': '192.168.10.0'

というエラーが出てしまいます。

こちらの記事を参考にhomestead.yamlのIPをip: 192.168.20.10に書き換えてみたのですが
今度は

と延々と接続にリトライしては失敗する状態が続いています。
恐らくSSHで接続が出来ないのだとは思うのですが、どこをどうすれば良いのかさっぱり分かりません。

vagrantfileは以下の通りです。
