I sent you a message about this. We had to block some IP address ranges to deal with a spammer, and your phone's address was in one of the ranges. You should be able to get in now. If not, it means your phone is using dynamic addressing, and you can try turning wireless or cellular (whichever you're using to connect with us) off-and-back-on to see if you get assigned an unblocked number.
Please let me know if you continue to have problems.
