Ghost hijacked my other subdomains

[Asitis]

I’m facing a rather infuriating issue. I have Ghost running on a domain on my Nginx server. I have multiple domains running all kinds of things on this server.

Ghost is running at domainA.com.
A WordPress install is running domainB.com
A nodeJS install is running om sub.domainA.com

Now I want to run a React app on sub.domainB.com but whatever I do, the sub.domainB.com keeps redirecting me to Ghost on domainA.com

I can’t “untie” Ghost from this subdomain no matter what I tried. I removed all related sites-directives, rebooted Nginx, created it anew, rebooted again, it still keeps pointing to Ghost.
I’m getting at the point to just delete Ghost alltogether just to get this shit to work

I have no clue why Ghost is taking THIS subdomain specifically, because no other domains do anything like this (note that the domainB.com I want to run the subdomain on isn’t even running Ghost at all).

This is the nginx server config for the subdomain: I’ve updated the ports to TRY and have Ghost not running on here, but whatever I do, it keeps showing up…

server {
        listen 6666;
        listen [::]:6666;

        root /var/www/subB;
        index index.php index.html index.htm index.nginx-debian.html;
        server_name sub.domainB.com;

        location / {
		try_files $uri $uri/ /index.php?$args;
		proxy_pass http://localhost:6666;
	}
	
	location ~ /\.ht {
		deny all;
	}

}

I’m going insane, what do I do?!

I’m running dozens of things along Ghost without a problem. And I’m getting a bit confused by that config you’ve posted.

Having Ghost running on local IP with port 2368, my Ghost config looks something like this:

server {
  listen 80;
  listen [::]:80;
  server_name example.com;
  root /var/www/ghost/system/nginx-root;
  client_max_body_size 50m;
  error_log /var/log/nginx/ghost/error.log;
  access_log /var/log/nginx/ghost/access.log;

  location / {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header Host $http_host;
    proxy_pass http://127.0.0.1:2368;
  }

Then a random site looks something like this:

server {
  listen 80;
  listen [::]:80;
  server_name example2.com;
  root /var/www/example2/public;
  error_log /var/log/nginx/example2/error.log;
  access_log /var/log/nginx/example2/access.log;

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

In your config, Nginx listens on port 6666 and then proxies itself for some reason, which makes no sense. Without looking into all the configs, I can’t think of a reason why it would behave like that. Are you sure you’re loading that config file? Have you tried to search the logs?
