React App with Nginx reverse proxy not displaying /swagger ; /redoc

So I've been trying to set up Swagger to work on /swagger/, it was working fine until we switched to a domain. I'm not that experienced with nginx and it's reverse proxy. I will share my settings, if anyone could help. It actually opens the page, but it's all white, same goes with /redoc/ (Redis).

Nginx.conf

        proxy_set_header        Host $http_host;
        proxy_intercept_errors  on;
    }

    location /ht/ {
        proxy_pass http://mysite:8000/ht/;
        proxy_redirect off;
        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        Host $http_host;
        proxy_intercept_errors  on;
    }

    location /swagger/ {
        proxy_pass http://mysite:8000/swagger/;
        proxy_redirect off;
        proxy_set_header        X-Real-IP $remote_addr;

        proxy_set_header        Host $http_host;
        proxy_intercept_errors  on;
    }

For example, /ht/ (health check) is working just fine

urls.py in backend:

urlpatterns = [ 
url(r'^swagger/$', schema_view.with_ui('swagger', cache_timeout=0), name='schema- 
swagger-ui')]

Please tell me if you need any other files, I'm willing to share them, I just replace sensitive data with dummy data like mysite.com

Thanks in advance!

Edit: I've just noticed that in Network tab, it shows for all CSS, JS files that "Javascript needs to be enabled to run this app", same goes for /redoc and also console log throws this: "Uncaught SyntaxError: Unexpected token '<'" for the JS files.

I've forgot to note it's a React App, but the App itself is working fine. Backend is in Python/Django So I've been trying to set up Swagger to work on /swagger/, it was working fine until we switched to a domain. I'm not that experienced with nginx and it's reverse proxy.
