I tried a lot with Nginx proxy that I could have admin panel (host:1337/admin) on proper domain.
But, I could not. I tried with /admin path to other app with proxy_pass. But, there were some paths that were not having /admin in them and they broke.
I created a subdomain and create nginx configuration. Now, I’m able to open my admin UI in separate subdomain.

# Listen HTTP
