phpstudy configures multiple sites

Question

就这一个电脑配置完多站点不能访问不到，配置文件都配置好了，其他电脑也没问题，是不是电脑需要配置什么权限

Answer 1

403? Could it be that the homepage file is not configured? Or there is no homepage file in the directory

Answer 2

Is the hosts file configured? What's the message when I can't access it? Basically it won’t be a problem with computer permissions
