Hello, I was following different guides to set up https on my nginx.
Right now my nginx.conf looks like this:

# HTTP SERVER
server {
        server_name  mysite.com;
        listen 80 default_server;
        listen [::]:80 default_server;

        location / {
            rewrite ^ https://$http_host$request_uri? permanent;
        }
}

# HTTPS Server
server {
    listen 443;
    server_name mysite.com;

    ssl on;

    ssl_certificate /etc/nginx/ssl/mysite.com.crt; 
    ssl_certificate_key /etc/nginx/ssl/mysite.com.key; 

    access_log  /var/log/nginx/client-access.log;
    error_log   /var/log/nginx/client-error.log;

    root /usr/share/nginx/html;
    index index.html index.htm;

    location / {
        try_files $uri $uri/index.html/index.html;
    }
}

When I test it I get the result:
nginx: configuration file /etc/nginx/nginx.conf test is successful

I deleted the firewall, so when I run:

sudo ufw status

I get:
command not found

After every configuration change I do:

service nginx reload

When I try to view a page via https, I see Chrome error page with ERRCONNECTIONREFUSED

If I run netstat -nlp | grep :443

tcp 0 0 0.0.0.0:443 0.0.0.0:* LISTEN 9683/nginx: master

I was wondering maybe my:
sslcertificate /etc/nginx/ssl/mysite.com.crt;
sslcertificate_key /etc/nginx/ssl/mysite.com.key;

are not correct, would I see any errors/logs if they were wrong?

I don’t know what else to check?
