This is beginning to spite me, I get the same exact problem. I tried the solutions you came up with, and yet they do not resolve this problem. I'm all go for asking an admin about this. It seems like one of the only options left to turn to. Although I'm not for it. My friend said it might be that there is too many people on the server, let alone she attempted to get into Ficho Tunnel with success but agreed that it was extremely laggy.
