I need someone to make configuration for nginx.conf

I need someone to configure the [login to view URL] for me. because as the reverse proxy for Apache does not load CSS or javascript on my part 
 Requirement: - Three upstream on the [login to view URL] example: “upstream docker-admin{ server admin:80; }” - The Location with sub path (so all my sub path can be open through port:44000) “ location /app/ { 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_pass http://api:5000; ###Service Name### proxy_read_timeout 90;” “ location /app2/ { 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_pass http://api:5000; ###Service Name### proxy_read_timeout 90;” “ location /app3/ { 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_pass http://api:5000; ###Service Name### proxy_read_timeout 90;” - all upstream can be connect to nginx port:44000 I need it until it can solve this "Apache does not load CSS or javascript". thank you in advance
