Laravel在nginx中提供502坏网关

我已经重新加载了服务器配置,以匹配Laravel上提供的配置。当我这么做的时候 php --ini 我可以看到我的PHP版本是7.0,所以我对7.0做了修改。

我的服务器配置如下所示:

server {
    server_name exoscape.co.uk;

    root /var/www/html/exoscape/public;
    index  index.php index.html index.htm;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location ~ \.php$ {
        include fastcgi_params;
        fastcgi_pass unix:/run/php/php7.0-fpm.sock;
    }

    location ~ /\.ht {
        deny all;
    }

    listen [::]:443 ssl ipv6only=on; # managed by Certbot
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/exoscape.co.uk/fullchain.pem; # manag$
    ssl_certificate_key /etc/letsencrypt/live/exoscape.co.uk/privkey.pem; # man$
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}

server {
    if ($host = exoscape.co.uk) {
        return 301 https://$host$request_uri;
    } # managed by Certbot

    listen 80;
    listen [::]:80;

    server_name exoscape.co.uk;
    return 404; # managed by Certbot
}

chmod 正确地执行以下操作:

sudo chown -R www-data:www-data /var/www/html/exoscape/
sudo chmod -R 755 /var/www/html/exoscape/

但我仍然收到502坏网关当我访问我的域名。我正在使用 nginx/1.15.12 . 任何帮助都将不胜感激。
