Are you connecting using Sockets? Sockets have restrictions on what they can access. See https://cloud.google.com/appengine/docs/java/sockets/
Paraphrased: Private, broadcast, multicast, and Google IP ranges are blocked, except those whitelisted below: - Google Public DNS: 8.8.8.8, 8.8.4.4, 2001:4860:4860::8888, 2001:4860:4860::8844 port 53 - Gmail SMTPS: smtp.gmail.com port 465 and 587 - Gmail POP3S: pop.gmail.com port 995 - Gmail IMAPS: imap.gmail.com port 993 tl;dr: Sockets-based connections cannot hit google.com from App Engine, with some exceptions.
