[3.x]: ETIMEDOUT after graphql requests

What happened?

Description

I'm using craft's graphql to generate a static site with a nuxt frontend. The generator manages to generate about 40 routes, then it returns

Error: Network error: request to https://geo-api.heimatschutz.ch/api failed, reason: connect ETIMEDOUT

and it doesn't generate the rest of the routes. Is there some configuration within craft that limits how many requests the api can receive? My php max_execution_time is already 30 seconds, I don't think that's the problem. but maybe there are other PHP variables I haven't thought about. The error is being thrown by apollo.

Thanks for any suggestions.

Steps to reproduce

1. set up craft graphql with some entry types and at least 50 entries
2. set up a nuxt frontend
3. run nuxt generate for custom routes in nuxt.config.js

Expected behavior

my routes would all be generated

Actual behavior

Error: Network error: request to https://geo-api.heimatschutz.ch/api failed, reason: connect ETIMEDOUT

Reproduce the Craft GraphQL and Nuxt generate setup with at least 50 entries and custom routes, then inspect where the Apollo request to the reported API times out. The issue is resolved when the cause of the timeout or request limit is established and a verified configuration change or fix allows all routes to generate.
