getaddrinfo is the function that resolves a domain name into an IP
address. If that fails, either the domain name doesn't exist or you have
a problem with your DNS setup.

Things to test:

* Can you resolve the domain name to an address (try «nslookup» or
  «host» or «dig» depending on your OS)?
* Can you access the whole URL with a different tool like «wget» or
  «curl»?
