vagrant up已启动正常，但是无法访问

==> my-project: Configuring cache buckets...

==> my-project: Updating /etc/hosts file on active guest machines...

==> my-project: Updating /etc/hosts file on host machine (password may be required)...

==> my-project: Machine already provisioned. Run `vagrant provision` or use the `--provision`

==> my-project: to force provisioning. Provisioners marked to run always will still run.

启动结果如上。查看virtualbox显示虚拟机正在运行。

但是访问显示连接被重置。

然后我用命令行http工具请求

http dev-tools.my-project.local/phpinfo.php

结果

http: error: ConnectionError: HTTPConnectionPool(host='dev-tools.my-project.local', port=80): Max retries exceeded with url: /phpinfo.php (Caused by <class 'httplib.BadStatusLine'>: '')

请问这是什么问题呢？
