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.
