After nginx sets proxy_pass, if the service of proxy_pass is not started, it will cause nginx to hang up.

use nginx to forward api requests. If the proxy_pass service is not started when setting proxy_pass , it will cause nginx to fail.

is there any way to ensure that nginx works properly when the backend service is down?

uses docker deployment
