How to proxy JetBrains products (hub, youtrack) via nginx?

Question

Nginx

Hello.
unable to set up JetBrains products on VPS. I have my own domain.
I wrote this in nginx config.

server {
  listen 80;
  listen [::]:80;
  server_name youtrack.djzt.xyz;
  server_tokens off;
  
  location / {
    proxy_set_header X-Forwarded-Host \$http_host; 
    proxy_set_header X-Forwarded-For \$proxy_add_x_forwarded_for; 
    proxy_set_header X-Forwarded-Proto \$scheme; 
    proxy_http_version 1.1;
  
    proxy_pass http://localhost:2224/;
  }
}
server {
  listen 80;
  listen [::]:80;
  server_name hub.djzt.xyz;
  server_tokens off;
  
  location / {
    proxy_set_header X-Forwarded-Host \$http_host;
    proxy_set_header X-Forwarded-For \$proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto \$scheme;
    proxy_http_version 1.1;
  
    proxy_pass http://localhost:2222/;
  }
}
server {
  listen 80 default_server;
  listen [::]:80 default_server;
  root /var/www/html;
  index index.html index.htm index.nginx-debian.html;
  server_name djzt.xyz;
  server_tokens off;
  
  location / {
    try_files \$uri \$uri/ =404;
  }
}

And now when I follow the link hub.djzt.xyz it redirects me to the link hub.djzt.xyz/http:///hub.djzt.xyz:80/hub and accordingly nothing works.
But the hub itself works at djzt.xyz:2222

The hub itself configured to listen on port 2222 and the base-url hub.djzt.xyz
I took everything from the article on habré
