For some background: To play Monster Hunter, after choosing the initial online mode (City), it does some connection work with a progress bar that fills up to 100%. After that, you're asked to agree to Capcom's terms of service, and from there, you choose a server to connect to. After choosing from a server that can hold 2000 people, you're asked to choose between one of several city gates, each capable of holding 100 people. From there, you choose an individual city, which can hold up to four people.
There have been times where I've been booted from a city, but not from a city gate, for whatever reason, and that's about as far as I can say to give background information without saying anything technical.
Regardless, it looks like Toruresu is stuck on the very first part, and is unable to even connect to Capcom's severs.
