Constantly crashing

I have been trying to log on for the last 2 hours. I will let me log onto any other planet apart from monster planet with is the planet I use. it will teleport me to the word and a second later it will make me crashed off it even if I don't move. Can u tell me how I can fix this. I have tried restarting Minecraft lots of times and restarting my computer but nothing is fixing it. I have tried going to every planet part from mine and they all seem to be working fine. Could you help me fix this bug
