Solved (CraftBukkit 1.4.2-R0.1) No one can log in but me.

Hello everyone!

I just switched from CraftBukkit 1.3.2-R2.0 to CraftBukkit 1.4.2-R0.1 and I thought everything was okay. I simply replaced the old CraftBukkit.jar with the new one, and I ran the server. Soon after announcing the server being back online, members told me the server was offline for them. It was strange because I was able to log in. What's going on? If you need any information, just ask!

Thank you so much!!

 

If you're running your server from home, you could have a static IP. You might have to check on that to make sure they're trying to connect to the correct IP address. If not, it's definitely a connection issue so check anything that regards to others connecting such as making sure the ports are forwarded correctly, your firewall isn't blocking your server port, etc.

 

YES! That was the problem. Thank you so much!!
