Minecraft – How to find lost account login email address

Solved it!

A meandering discussion on the Talk page for the server.properties article on the Minecraft Wiki indicates that this is Forge's fault. Apparently it redefines spawn-protection to be a boolean that turns protection on or off entirely (which you can't do in vanilla), and defines a new variable, spawn-protection-size for what the former variable means for a vanilla server.

As a side effect, it appears that a server with the Forge API installed will honour the default spawn-protection area of 16 blocks until you edit the variable, at which point it treats it as boolean and looks for spawn-protection-size instead, doesn't find it, and effectively turns spawn protection off entirely.

So this is what happened to me then. Adding spawn-protection-size=42 to my server.properties file made spawn protection work (again) as expected. Redefining configuration variables is poor practice!

There is a number of things you should rule out first:

• Are you able to login through http://account.mojang.com/login?

• Are you using the proper client from http://minecraft.net/download?

• If you were able to login with your old computer; make sure your current one doesn't have any firewall blocking internal / external connections.

• On the computer with the issue, do the following:

  : Go to this url, and substitute USER for your actual username and substitute PASS for your actual password.

  : It should output a Session ID (a bunch of numbers and letters), if not; and it returns Bad login or another exception; contact mojang.
