Tool drawing and regeneration is client side and won't be affected by firewalls
on your server.
I'm not familiar with the ASPX plugin but that error looks similar to the PHP
"could not open socket" error. The two most common causes of that error are
firewalls that block outbound HTTP ports at the server and app
servers/frameworks that have been configured not to allow outbound connections.
If you have access to the server can you open http://74.125.227.18/ in a
browser or run "telnet 74.125.227.18 80" in a terminal? If so, does it
connect?
