Nginx throws 404 when trying to access the service

When i am trying to connect one of my services i get
404 Not Found nginx.
I’ve configured dockerfile and docker-compose well, but have some issues on nginx configs side

the project structure is

./backend/subscription_service
./backend/subscription_service/Dockerfile
./nginx/nginx.conf
./docker-compose.yaml

Nginx log:

2025/06/08 09:24:32 [error] 22#22: *2 open() "/etc/nginx/html/index.php" failed (2: No such file or directory), client: 172.18.0.1, server: localhost, request: "POST /subscription/subscriptions/ HTTP/1.1", host: "localhost"
