As Barry has said, a getaddrinfo failed error would indicate an issue on your side with resolving the address, not an issue on Twitch’s side.
Also, when you say you’re continuously asking for data, how frequently are you hitting the endpoint? All Twitch API endpoints use caching so if you’re requesting the same resources more frequently than once a minute you’ll be getting back cached data some of the time and just wasting requests, and if you’re only waiting a few seconds between requests you can even get erroneous data by hitting different cache servers and getting data out of order.
