The server IP is mc-gtm.net. Edit by a moderator: You must use the IP 'gtm.network' to connect to the server now!
It appears like your attempting to join the server on mobile. If this is what you are trying to do I am sorry to inform you that you can unfortunately not join Grand Theft Minecart on mobile right now. If you would like to play on mobile I would suggest you create a forums post and suggest that they come out with a mobile version. However, I don't know if this is possible because with mobile you have a lot less room to code and program plugins and servers.
