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.

Hi there,

According to the official documentation, the managed Load balancer connections have a keep-alive time of 60 seconds:

Can you verify if you are able to execute your requests correctly if you make them against the Nginx service directly rather than going through the Managed Load Balancer?
