proxy_timeout

Timeout for upstream requests to the origin.

Default
45

The maximum time the proxy waits on an origin before giving up on a request. Too low and slow-but-valid responses are cut off; too high and a stuck backend ties up resources. The default is 45 seconds.

Tune to your workload
Lower it for snappy APIs so failures surface fast; raise it for endpoints that legitimately take a while (report generation, large uploads).
