Issue with pgAdmin 4 Login Behind NGINX Reverse Proxy at /pgadmin4 Path

Hi,

I've installed pgAdmin 4 on my Linux server and configured it behind Gunicorn and NGINX, accessible at:
https://domain.com/pgadmin4/.

The login page loads correctly. However, after entering valid credentials, I'm redirected back to the login page without any error message. Occasionally, I see a CSRF token error, which disappears after a page refresh, but the login still fails.

In the browser console or network tab, I sometimes see 401 errors or issues loading static assets.

Here's the NGINX configuration I'm currently using to reverse proxy pgAdmin via a Unix socket:

nginx
location /pgadmin4/ {    proxy_pass http://unix:/tmp/pgadmin4.sock:/;
    # Proxy headers    proxy_set_header Host $host;    proxy_set_header X-Real-IP $remote_addr;    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;    proxy_set_header X-Forwarded-Proto $scheme;
    # Inform pgAdmin it's served under a subpath    proxy_set_header X-Script-Name /pgadmin4;
    # Optional: timeouts and static asset handling    proxy_read_timeout 300;    proxy_connect_timeout 60;
}

Could you please advise:

1. Is there something wrong with the proxy setup?

2. Do I need to handle static assets or cookies differently when using a subpath (/pgadmin4)?

3. Are there any additional settings required in the pgAdmin config to work correctly behind a sub-URI with NGINX?

Thanks in advance for your guidance.
