Failing to test APIs, getting getaddrinfo EAI_AGAIN error

I am on the Test the APIs chapter, everything has gone well so far but I keep getting this error after I try testing with the aws-api-gateway-cli-test package.

npx: installed 106 in 8.335s

getaddrinfo EAI_AGAIN

This looks like a DNS related issue? Can you ensure your local computer is working properly for other websites?
