The first thing I would recommend changing is this server block:
server {
listen 80;
server_name linuxhowto.tech;
location / {
return 301 https://$server_name$request_uri;
}
}
When it comes to HTTP -> HTTPS redirects, you don’t need to specify a location block. All you need to use is:
server {
listen 80;
server_name linuxhowto.tech;
return 301 https://$server_name$request_uri;
}
Beyond that, I just setup and ran a test installation of Ghost + NGINX using your Proxy Config and it’s working without any issues, so it may be the above that’s causing the issues.
So for you domain, you should have two server blocks that look like:
server {
listen 80;
server_name linuxhowto.tech;
return 301 https://$server_name$request_uri;
}
server {
listen 443 ssl;
server_name linuxhowto.tech;
ssl on;
ssl_certificate /etc/letsencrypt/live/linuxhowto.tech/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/linuxhowto.tech/privkey.pem;
ssl_prefer_server_ciphers On;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers ECDH+AESGCM:DH+AESGCM:ECDH+AES256:DH+AES256:ECDH+AES128:DH+AES:ECDH+3DES:DH+3DES:RSA+AESGCM:RSA+AES:RSA+3DES:!aNULL:!MD5:!DSS;
location / {
proxy_pass http://localhost:2368;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_buffering off;
}
}
I went ahead and restarted the droplet but somehow made the problem change to this:
502 Bad Gateway
LOL. From sort of working to flat out broken.
Are you running Ghost on port 80, or trying to, or are you using a web server such as NGINX/Apache to proxy requests to http://localhost:2368?
If you’ll post your config.js (comment out sensitive data) and, if using web server, the VirtualHost or Server Block details, we can take a look at those configurations and see what we can find.
