I haven't played in a while. Maybe that's the problem? When I attempt to join the server I get a "lost connection" error message. I'm sure the address is correct. My son is beside me playing on the server, so its not my internet. It could be something with my computer but I have not idea what. HELP?
Make sure you are using server.sandlotminecraft.com for the Server IP/Server Address and using Minecraft 1.12.2.
