I can’t load parse dashboard through domain, hosted in digitalocean vps - ubuntu 20.04
full (strict) ssl - cloudflare

dashboard is accessible through direct IP address access - “htt p://ipaddress:4040/login”

nginx - reverse proxy enabled for dashboard and server, reverse proxy working for parse server but failing on dashboard.
when i try to load “htt ps://mydomain.com/dashboard” - it redirects to “htt ps://mydomain.com/login” with 404 Not found page

nginx config on /etc/nginx/sites-enabled/domain.com

# HTTP - redirect all requests to HTTPS
server {
    listen 80;
    listen [::]:80 default_server ipv6only=on;
    return 301 https://$host$request_uri;

parse server is working through both domain and direct ipaddress:1337
parse dashboard is only available through ipaddress:4040 and it’s working fine

when i try to access using https://domain/dashboard/ it is redirected to https://domainname.com/login and showing a 404 page
1337, 4040 ports are open
  location /dashboard/ {
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-NginX-Proxy true;
        proxy_pass http://localhost:4040/dashboard/;
        proxy_ssl_session_reuse off;
        proxy_set_header Host $http_host;
        proxy_redirect off;
still the same results.  I’m pulling my hair …

its driving me crazy for past 3 days.
          
I’m sorry to bother you again, I’m a newbie in backend and server management, I really don’t understand what you meant by
MOUNT_PATH needs to be an env var
I used JSON to config parse and used nohup to run the server.
it is redirecting to https://domain.com/login (404 not found) when I enter https://domain.com/dashboard i  really don’t under stand why its happening.

It will be really helpful if you can point me to the right direction.

Thank you
          
Just an idea:

Try changing this statement in Nginx’s config:

proxy_pass http://localhost:4040/dashboard/;

To this:

proxy_pass http://localhost:4040/;
Then restart Nginx and try accessing your dashboard again.
