Vagrant up 和 ssh 無法在學校網路上運行

Question

我透過 WiFi 連接到學校的網絡，當我嘗試連接vagrant up或vagrant ssh收到以下訊息時：

流浪向上

==> default: Waiting for machine to boot. This may take a few minutes...
    default: SSH address: 127.0.0.1:2222
    default: SSH username: vagrant
    default: SSH auth method: private key
    default: Warning: Connection timeout. Retrying...
    default: Warning: Connection timeout. Retrying...
    default: Warning: Connection timeout. Retrying...

流浪者 ssh

ssh_exchange_identification: read: Connection reset by peer

我怎樣才能解決這個問題？
