Only if at least 5 other people at the same internet cafe are on Hive at the same time. (Or more than 5 connections are open to the Hive from the same internet cafe.)All internet cafes share a same IP address. You can't visit Hive from a Cafe that has more than 5 PC's
This specific problem might also be caused by a software firewall or other security software use on the internet cafe computers.
Are other people on the cafe also on? Everyone may be sharing the same IP and gets blocked because of the max connection limit of 5.
