Your script is running fine. As you can see from the error message, your 
web proxy firewall is not allowing you to access the ebi website (can 
you visit http://www.ebi.ac.uk/cgi-bin/dbfetch in a web browser on the 
same machine?). You'll need to get in touch with the 'firewall admin', 
or change web proxy.
