Looks like you have some networking issue:
Do you have anything custom set up in the hosts file pointing to 127.0.0.1 perhaps? Any other networking issues?
Can you please do a traceroute to api.paradoxplaza.com and api.paradox-interactive.com and let us know what you see.
I'm sorry for the late reply, just managed to see this now.
I will do it today and post the results.
