Now you've probably heard this alot, but I looked everywhere andnone fixed the problem. Whenever I try to join a server (And I am typing in the correct IP address) It always says Bad Login. I've tried this with multiple servers, so I know the problem isn't the server it's my computer.
So, do you know how to fix this?
(P.S. I've also heard of Hamachi. What is it and do I need it)
If your in-game name is SizzlingCreeper, you haven't got the premium/paid version of minecraft, instead a pirated version.
Basically, the server is saying that you are not a premium server and won't allow you onto their server.
You have to either buy minecraft from the official website, or join 'cracked' servers.
If you are running a server, when you run the server in the server.properties file you can change 'online-mode=false' to allowed cracked players. Be aware that anyone can logon to anyones account on your server. Some people might not who you think they are.
Hamachi is the weak way of portforwarding and letting people join your router. If you know how to portforward, you won't need it. I recommend learning to portforward so you can help other people out because they can't read, and you'll get to know your router better.
