If you are having troubles logging in, you can try the creative IP (creative.mcpz.net). Also, if you get a disconnected message it's usually because of your connection, I recommend restarting your wifi. Re opening minecraft because it mainly has to do with your connection.
If you are still having issues logging in feel free to private message me on the forums, or ask another question.
If you have any further questions, don't hesitate to ask!
