SourceBans applies a short local ban to avoid having to re-query the DB, but I'm not sure you're actually banned because that pops up a very obvious message and doesn't just retry.

Can you post the console output you get when trying to join?

Are you the owner of the server or are you just a player? Because if not you should probably be talking to them not us, only they know what they have set up.
