It would be best to ask your IT department whitelist app inventor. Please see

List of URLs and Addresses that App Inventor Uses

The following URLs are the ones you most likely want to whitelist: Main servers: http://ai2.appinventor.mit.edu/ and http://code.appinventor.mit.edu/ Login server: http://login.appinventor.mit.edu Rendezvous (for establishing live testing connections): http://rendezvous.appinventor.mit.edu If your teachers use CloudDB as part of their curriculum, you'll also need to whitelist connections to clouddb.appinventor.mit.edu on port 6381.
