nginx reverse proxy

Make sure reverse proxy can work, especially check the case below:
```
http {
server {
listen 80;
location /foo/ {
```

The location is not just `/`.

Look for nginx configuration files in the project, likely in a deployment or infrastructure directory. Test the reverse proxy setup with a location path like `/foo/` to ensure it routes correctly, not just `/`. Check if there are existing tests or documentation for the proxy configuration to understand the expected behavior.
