安装新的 SSL 证书后，我的网站出现 ERR_TUNNEL_CONNECTION_FAILED

Question

我的网站groceryshoptest.com托管在Digital OceanDroplet 上，并配有Nginx服务器。我使用了免费的 SSL让我们加密 certbot，我刚刚输入了一些命令，在etc/nginx/sites-available/groceryshoptest文件中添加了一些配置并安装了证书，一切运行正常。后来我决定将服务器移至Linode。所以我停止了之前的服务器，将 DNS 指向我的新服务器地址，安装了所有东西，它运行正常。然后我再次在新服务器上http安装了证书。它显示一切都已成功安装。所以我的问题是，我可以从访问该网站，但无法从以下浏览器中访问LetsencryptLinodeBangladeshUSA

ERR_TUNNEL_CONNECTION_FAILED

我的配置文件在这里

 server {
    server_name groceryshoptest.com;
    root /var/www/html/shop;
    index index.html;
    location / {
        try_files $uri $uri/ /index.html?$args;
    }

    listen [::]:443 ssl; # managed by Certbot
