Success is over rated

Yes I found that, what I was saying is that it tells you to put in the clan name to leave and it isn't working for me.

I have been trying to leave the clan I am currently in but I have tried the clan name and several combinations of the clan name and nothing is working Any suggestions?

I am not able to log in to the game. It gives me

invalid json response data:
ERROR 521

I have tried closing out the window, rebooting the game, but nothing is working.
