404 errors (assets) on Subfolder installation

I have made the changes and it’s still the same. My configs are given below. I am using Centos 7 with overlay2 as device storage driver.

Nginx reverse proxy:

location /community {
                pagespeed  off;
proxy_set_header X-Forwarded-Host $host;
proxy_set_header X-Forwarded-Server $host;
proxy_set_header X-Forwarded-For $remote_addr;

proxy_set_header X-Forwarded-Proto $scheme;

proxy_read_timeout     3600;
proxy_connect_timeout  240;
proxy_set_header Host $host;
proxy_set_header X-RealIP $remote_addr; #Important line for our logging objective

## End This is ProxyPassReverse for Nginx

proxy_pass http://127.0.0.1:25654$request_uri;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}

app.yml

run:
    - exec:
        cd: $home
        cmd:
          - mkdir -p public/community
          - cd public/community && ln -s ../uploads && ln -s ../backups
    - replace:
       global: true
       filename: /etc/nginx/conf.d/discourse.conf
       from: proxy_pass http://discourse;
       to: |
          rewrite ^/(.*)$ /community/$1 break;
          proxy_pass http://discourse;
    - replace:
       filename: /etc/nginx/conf.d/discourse.conf
       from: etag off;
       to: |
          etag off;
          location /community/ {
             rewrite ^/community/?(.*)$ /$1;
          }
    - replace:
       filename: /etc/nginx/conf.d/discourse.conf
       from: etag off;
       to: |
          etag off;
          location /community {
             rewrite ^/community/?(.*)$ /$1;
          }
    - replace:
         filename: /etc/nginx/conf.d/discourse.conf
         from: $proxy_add_x_forwarded_for
         to: $http_fastly_client_ip
         global: true

    - exec: echo "End of custom commands"

Could you please send me the last part of your YML config i.e. -exec…
