I have been trying to use the Ethernet Shield to read an xml feed to control an arduino. I have tried it on my own, as well as through pachube.com, all to no avail. I can tweet via the ethernet shield, so I know my network settings are correct, but as soon as I try to connect to the internet to read an xml feed, it fails. Setting things up through pachube, I can send data to the site, but it refuses to read the xml feeds.
Using Serial.printIn to debug, the code gets to client.connect() at which point it fails. I have been trying to get a simple script going that will pull the robots.txt file from any IP address, but nothing seems to work. Any help/guidance anyone can provide would be appreciated.
