The Misconfigured Proxy

A Python reverse proxy is supposed to forward requests from port 3000 to a backend server on port 8080. However, the proxy's configuration file has the wrong upstream port (9999 instead of 8080), so all requests fail. Fix the config file at /opt/proxy/config.json and wait for the proxy to automatically restart (it reloads every 15 seconds). The watcher will check that curl http://localhost:3000 returns 200.
