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:

Is there something wrong with the proxy setup?
Do I need to handle static assets or cookies differently when using a subpath (/pgadmin4)?
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.

Hi,

Can you please share your guicorn command?

How many workers are you spawning? It should be 1.

Thanks,

Hi,

Thanks, it worked.

I am facing an issue when I try to access the pgadmin of https after logging in; it shows a blank page. Can you please help me figure it out?

This is the config I am using for the proxy in HTTPS and HTTP vhblock

location = /pgadmin4 { rewrite ^ /pgadmin4/; }
location ^~ /pgadmin4/ {
proxy_pass http://unix:/tmp/pgadmin4.sock;

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;
proxy_set_header X-Forwarded-Host $host;
proxy_set_header X-Script-Name /pgadmin4;
proxy_http_version 1.1;

proxy_read_timeout 300;
proxy_connect_timeout 60;
}

In the browser console of I am getting this error.
Object { message: "Request failed with status code 401", name: "AxiosError", code: "ERR_BAD_REQUEST", config: {…}, request: XMLHttpRequest, response: {…}, status: 401, stack: "".....

Hi,

You can use the command 'update-user' for user update.

To explore more options, you can use the command below with pgadmin venv.

`python3.12 setup.py update-user --help `

Typical command would be -

`python3.12 setup.py update-user <user_id> --password <new_password> --role Administrator --sqlite-path <pgadmin_db_path>`

Hi,

I hope you're doing well.

pgAdmin is now working properly. Earlier, I ran the setup-db command and set the admin username and password.

Now, after reinstalling pgAdmin, I noticed that the data directory (including pgadmin.db) was not removed. I would like to either reuse the old admin password or reset it if needed.

Is there a way to reset the admin user's password using a command in this case?
Your guidance would be greatly appreciated.

Thank you for your help.

Hi,

I could reproduce the error when I have multiple workers. Maybe you can try restarting the Guicorn service.
Can you please try once in the private browser window?

HI,

I have used this command, and I have created a systemd file to start and stop the service.

ExecStart=/var/w-data/pgadmin4/pgadmin_venv/bin/gunicorn \
--workers 1 \
--threads=25 \
--bind unix:/tmp/pgadmin4.sock \
--chdir /var/w-data/pgadmin4/pgadmin_venv/lib/python3.11/site-packages/pgadmin4 \
--umask 007 \
pgAdmin4:app

Also, when I try multiple times then it will log in and show a blank dashboard, or sometimes it will show a dashboard but not work properly. In the console log, I see the following error
