安装 LetsEncrypt ssl 证书时出现“无法安装证书”错误

Question

我正在尝试安装 Lets Encrypt，但没有成功。我收到以下错误：

Keeping the existing certificate
Could not reverse map the HTTPS VirtualHost to the original

IMPORTANT NOTES:

Unable to install the certificate
Congratulations! Your certificate and chain have been saved at: /etc/letsencrypt/live/www.deals4u.co.il/fullchain.pem Your key file has been saved at: /etc/letsencrypt/live/www.deals4u.co.il/privkey.pem Your cert will expire on 2018-05-19. To obtain a new or tweaked version of this certificate in the future, simply run certbot again with the "certonly" option. To non-interactively renew all of your certificates, run "certbot renew"

我的 conf 文件是这样的：

<VirtualHost *:80>
    ServerName deals4u.co.il
    ServerAlias www.deals4u.co.il
    DocumentRoot /var/www/html
    <Directory /var/www/html/>
        Options Indexes FollowSymLinks
        AllowOverride All
    </Directory>
</VirtualHost>
