Nginx Docker 504 Gateway Timeout after 60 seconds

We have a full docker container build with a digital ocean load balancer, an nginx webserver and a reverse proxy to the backend node container for api calls.

We are trying to make api calls in bulk for a nextjs page build and the connection is timing out after 60 seconds.

We’ve tried all of the normal things: updating the nginx.conf settings in the http heading, updating the nginx conf.d default server blocks with proxy settings increased, etc.

How do I increase the timeout time for api calls to the server? when we lower the values in these locations the settings work, but they do not expand beyond 60 seconds.
